An Anniversary 

Til is issuL- begins our seven tli vcar of 
publishingy4»)(i;/«_j&i"i/J»//M^^;. That means we 
ha%'e created over 70 monthly issues (the first 
year AC published nine issues in eleven 
months), seven AC Ctiidcs, and five issues of 
/IC's TECH. That is a l«t of paper- and many 
memories. 

It's always easy at these times to review 
past successes and speak of the future. After 
ail, when we started this magazine, our belief 
in the Amiga blinded us from llie common 
understanding that a small company staring a 
new computer magazine would certainly fail. 
It was the Amiga that drew our interest and 
prompted us to dedicate our joLis, our money, 
and our lives to provides magazinecreated to 
capture the magic of the Amiga for everyone. 
The Amiga attracted us, kept us entertained, 
and truly amazed us. This was the wonder we 
wanted to demonstrate for everyone else. We 
have kept that same amazement. 

Video, animation, sound and music, and 
even business use of the Amiga has changed 
dramatically. I felt a bit of this vertigo recently 
\vhile I ivas rummaging through some dis- 
continued software bins at Toronto's World of 
Commodore. !5tate-of-the-art packages only a 
few years old ha\'e become ctillectors' items 
toda\'. Products created and marketed by major 
companies to provide presentations, music, 
and art have all been surpassed by the conti nual 
evolution of software developei's. 

This is true not only of software devel- 
opers. Items such as the new fax a nd voice ma ii 
capabilities demonstrated by Great Valley 
Products in Toronto again show us the Amiga 
is capable of more than what we could have 
imagined. 

What does this mean? Can we guess the 
future from a view of the past? Sometimes this 
is possible, but I must confess, I am not good at 
second guessing the inno\ationsand genius of 
Amiga de\'etopers. They constantly go further 
than I expect. Some market conditions of today 
can give us a view of what the future possibly 
holds. 

Is 1992 the Year of the Amiga? 

Sometimes the events of the world over- 
whelm everything else. The Soviet Union, a 
long-standing major power, has dissolved. In 
its place has been created a loosely constructed 
commonwealth of independent states. These 
states were created from the original countries 



and regions that made up the Soviet Union. 
Whether or not this form of government u'ill 
be the final organization is not central to our 
thinking. What is important is the apparent 
complete change from a socialist economy to a 
market-driven one. 

The people of the old Soviet Union cur- 
rently have a great deal more pressing matters 
than the notion of computers — food, housing, 
fuel, distribution, communication, education, 
and a true economy. It is important to guess 
how they will solve their problems. Tor the 
most part, hard work is the apparent answer — 
growing food in the fields, establishing 
manufacturing sites, and building shipyards. 
While the former Soviets have always lived 
under a different system of work ethics and 
rewards, the truth is that they have always 
labored hard. The Soviets have struggled for 
some time with less equipment and feu'er re- 
sources than their American counterpartsand, 
while not often excelling in their efforts, they 
have always managed to survi\'e. 

Just a short time ago, Germanv pushed 
asideallthcblocksthatkcpt it adivided country 
to become u nified once again. Th is \vas done i n 
no small part by the absence of any interven- 
tion bv the Soviets. It also led the way for the 
.'\mign to be introduced into what was once 
Kast Germanv by the people v%'ho were tlien 
called West Germans. Currently, thcreareover 
a million Amigas in use in Germany with a 
great number of these finding their way into 
the eastern portion of the country. Can the 
same strong interest in the Amiga be ascribed 
to the former Soviets? 

Post-Soviet nations will be searching for 
ways to solve their problems. Although the 
Amiga is known throughout Hurope as a very 
good game machine, it is also recognized as a 
verv good computer. This knowledge and the 
price le\'els of the Amiga will not bo lost on the 
former Soviets. 

In a country' where millions of people 
must be trained well, immediately, and eco- 
nomically, will they lie looking at the features 
of the Amiga and CDTV? In a country where 
information must he transferred quickly and 
where television is still a government-owned 
concern, will they demand the advantages of 
some of the Amiga video productsavailahle in 
PAL? 

The Amiga will not solve all the problems 
of the peoples of the dissolved Soviet Union or 
Eastern Europe, but it is a valuable tool for 



allowing them to educate themselves and it is 
available now when they need it most. Imag- 
ine instruction for young engineers or farmers 
created on CDTV. The best processes and in- 
structions can quickly become second nature. 

Imagine a small farm community where 
a video tape is plaved that describes and il- 
lustrates diseases and care tor larm animals. 
Almost every person studying the tape would 
ha\'e an immediate understanding of the dis- 
ease and its treatment. Prom showing how to 
preserve food to crunching numbers for road- 
building projects, the Amiga could well be the 
best tool for a full recovery these people could 
have. Through static videotaped presentations 
or interactive soft\vare, the Amiga has the 
ability to reach all people with sound and 
graphics, and make learning available to ev- 
eryone. 

Mowever, after thev have conquered their 
major problems, will they turn to the Amiga? 
Imagine the wealth of software that could be 
generated by an entire commonwealth of 
countries pushing the envelope of what they 
do and how the\' do it? 

Is This the Change Now? 

This week Commodore's stock took an 
amazing jump from S12 a share to $18. A good 
many financial anal vsls have "discovered" the 
Amiga and Commodore as a good investment. 
CI3M has received good press concerning 
CDTV and the Amiga from such magazines as 
/.?[(.■;/»('.•;« VVrt'fc (December 16, PJyi) and Pojniliir 
Mi'cliiinia (December I'Wl). NewTek made 
the Discover magazine's list of top 50 science 
articles for 1991 — as well as getting a blurb on 
the front cover. Is this the year of the Amiga? 
Mas it gained the respect that will inform the 
public what the Amiga can do? 

Just as the peoples of the post-USSR will 
need more time, dedication, and assistance to 
create a better life, we Amiga owners will also 
need to work hard toward our goals. However, 
it is satisfy ing to see how fa r we have been able 
to go, and it is always fun to anticipate the 
changes on the way.

8 Amazing Computing 




HINKALi'040 
ACCELERATORS ARE THE SAME? 

THINK AGAIN! 



As a high power AmigeF 3000/3000T 
user you need a 68040 accelerator 
board for one reason ...and one 
reasononly... SPEED! 

And once you know what makes one 
68040 accelerator better than another, 
the only board vou'll want is the 
G-FORCE 040 from GVP. 

I/VATGH OUT FOfl SLOW DRAM BOniBiECKS 

Yes, all 68040 CPU's are created equal 
bin this doesn't mean that all accelerator 
boards allow your A3000 to make the 
most of the fi8040 CPU's incredible 
performance. 

The A3000 was designed to work with 
low-cost, 80ns DRAM [memoryl tech- 
nology. As a result, anytime the '040 
CPU accesses the A3000 motherboard, 
memory lots of CPU wait-slates are 
introduced and all the reasons you 
bought your accelerator literally come 
to a screeching halt! 

Not true for the G-FORCE 040... 

SOLUTION: THE G-FORCE 040's FAST, 40tis, 
ON BOARD DRAM 

To eliminate this memory access bottle- 
neck, we designed a special IMU, ,12-hit 
wide, lion- multiplexed, SIMM module 
using 40ns DRAMs (yes, forty nano- 
sccomhU. This revolutionary memnry 
module allows the G-FORCE 040 to be 
populated with up to 8.MB of state-of-the- 
art, high performance, on-board DR-AM. 
Think of this as a giant S.MB cache which 
lets the '040 CPU race along at the top 
performance speeds you paid for.

X-oR 

UNIVERSAL SYSTEM EXCLUSIVE 
ORCHESTRATOR 

by Rick Mmwsa 



A lot of 
thought has 
gone into this 
program's 
purpose and 
design, 



The basic X-oR screen 
displays the Perfomance 
window. xoR VI. 3b 



X-oR is n fiill-foatured uni- 
versal system-exclusive editor/ 
librarian pacltagL' from Dr.T's that 
promises to help ma.ximize your 
MIDI setup in a \ariety of ways, ft 
will help you organize your 
sounds, create new sounds, edit 
and audition sounds while edit- 
ing; and it will do all of this for 
every piece of MIDI equipped gear 
you ovvn. That's a lot of good stuff 
in one package. Let's see what the 
good Doctor and his Caged Artist 
have come up with. 

X-oR comes on three non- 
copy-protected disks with a 
manual in the standard Dr, T's 
mini .i-ring binder. One disk con- 
tains the program and related files 
while the other two contain Pro- 
files for a wide range of instru- 
ments. A Profile — sometimes 
called a dri\'er or a template — is a 
file (hat provides all the technical 
information about a particular in- 
strument that X-oR needs in order 
to communicate with the instru- 

MeRGC:Marn 



nieiit. Dr. T's pumps out more 
Profiles as new instrumenls are 
introduced. Tliis is !iow X-oR can 
claim to he a "universal" editor 
librarian. The fact that you can 
exchange Dr. T Profiles across 
computer platforms lends cre- 
dence to the claim as well. 

The first chapter goes over 
terminology and conventions. X- 
oR uses a hierarchical structure of 
Machines, Instruments and Mod- 
ules. A Machine is what we would 
call an instrument. It is the physi- 
cal MIDI device — a D-50, a Pro- 
teus, etc. An Instrument can be 
equivalent to a Machine, but isn't 
necessarily so. An Instriunent is a 
Machine, or that part of the Ma- 
chine, that uses one Profile. Some 
Machines may use only one Pro- 
file. Others mav have a Profile for 
sounds, one for built-in effects, 
one for a software patch bay, etc. 
The final component, the Module, 
corresponds to a single patch edit 
buffer in an Instrument. This is the 
part of the instrument that uses 
patch data. A patch is any collec- 
tion of paramaters that make up a 
sound file, drum kit, tuning table, 
etc. This system allows for a great 
deal of flexibility and can cut de- 
velopment time for new Profiles. 

Customize to Suit Your 
Working Style and 
Hardware System 

Installationand setup is well 
explained and should cause no 
p roblems. You can customize how 
X-oR operates to suit your work- 
ing style and hardware svstem. It

was very easy for me to set up my 
X-oR files on the Music partition 
of my hard drive, lea\'ing the pro- 
gram files on the Work partition. 
It can gel a bit confusing, though, 
if vou use a sy nth that has multiple 
profiles. If you use a TX-8IZ, for 
example, vou must copy all the 
files that start with TX-81Z --TX- 
SIZ.XOR, TX-81ZEFX.XOR, etc. 
Sometimes there's more than one 
version of a Profile for an instru- 
ment. The i'roleus XR has two set- 
ups— PROTXKl and PROTXR16. 
You 11 ha\'e to read the .HLP files 
to determine which is best for you . 
Another wrinkle appears if you 
ha\'e more than one of a particula r 
synth. If you have two MT-32's, 
forexample,you must copy all the 
MT-32 files twice. Luckily, none of 
the Profiles are very large. You 
should be able to fly with even the 
smallest of storage systems. 

X-oR can further automate 
your work if you have a program- 
mable MIDI switcher. A MIDI 
sivitcher allows you to switch be- 
tween user-assignable configura- 
tions that can tell your .MIDI sys- 
tem any number of things. You 
can set up one configuration to 
define your main keyboard as 
master foi' your whole system, and 
another that puts the Amiga in 
charge. Some switchers \vill also 
let you filter out MIDI data (pitch 
bend, aftertouch, etc.), transpose 
notes, change the MIDI channel, 
etc. X-oR can be set up to switch 
between your different synths au- 
tomatically through your pro- 
grammable switcher. You won't 
have to rim o\'er (o your rack one 
minute to make the Amiga talk to 
your DX-7, then run over a little 
later to have it talk with your MI. 
X-oR will work just as well with- 
out a sivitcher, but it can make life 
easier for you if you do have one. 

A note here about technical 
support. 1 had a problem setting 
up my MSB+ switcher for X-oR. It 
took me a couple of days calling 
on and off to connect v\'ith the 
technical support crew at Dr. T's. 
While that is not the ideal situa- 
tion, once 1 did get through, 1 got 
all the help 1 needed. The staff is 
knowledgeable about their prod- 
ucts and courteous to the user. 
The additional suggestions ihev 
offoi-ed saved me all sorts of head- 
scratching time. 



JS Amazing Computi.\g 



Onco the switcher is config- 
ured, viui must sot up your instru- 
ments. This inv'iiives lulling X-oK 
which MIDI and SysEx channel 
each instrument is connected to. If 
you are using n switcher, you're 
also asked to enter the program 
number on the switcher that w\[\ 
routecommunications toand from 
each instrument. X-oR needs to 
know if von hn\c more than one 
identieaHnstrument on anv SysEx 
channel and on xvhich channel 
your switclier accepts program 
changes before you can save the 
defaults. This whole process 
shouldn't take more than a half 
hour or so. You can create and 
save as many setup variations as 
you like. Once these one-time set- 
ups are complete, \'ou're read}' to 

SO- 

X-oR makes good use of the 
mouse for auditioning sounds. 
You won't have to reach for your 
ma.ster ke\'board whcnc\'cr vou 
want to check an edited sound. 
Instead, you can click on the right 
mouse button and hear the sound. 
Pitch and velocity are position 
dependent. Moving the mouse to 
the right or left ivill raise or lower 
the pitch. Moving it up or down 
increases or decreases velocity. 
The Shift key duplicates the play 
function of the right mouse but- 
ton. The Ctrl, Alt, and Left Amiga 
keys serve as modifiers that add 
glissando, pitch bend, and control 
changes to [he note being played. 
This is reminiscent of Laurie 
Spiegel's program Music Mouse. 
The ergonomics of this setup, 
cotiplod with the 1 3differcntscales 
available in all 12 ke\'s, makes for 
a lot of easy fun and creative ex- 
ploration. 

.MIDI merging is a term that 
refers to using two MIDI devices 
as master controllers at the same 
time. X-oR realizes that you will 
want to control \'i>urmodulesfrom 
both the computer and vour mas- 
ter keyboard without ha\ing to 
repatch cables, and pro\'ides you 
with three merging options. Basic 
Merge passes data on all chann,?ls 
through the computer. This means 
that you can hear a sound by 
plavingyourmasterconfcroUerand 
also bv using the aforementioned 
right mouse button orshift key on 
the Mouse Channel without hav- 



ing to repatch your system. Solo 
Merge only merges data from the 
designated Mouse Channel with 
the output of X-oR. This option 
operates like the solo button on a 
multitrack mixing board and 
would be useful for monitoring 
individual channels of a se- 
quencer. Rechannelize Merge 
merges the input from all 16 
channels, then routes the output 
to the Mouse Channel. This auto- 
mates the switching of the otitput 
of vour master controller. Just click 
on the sound module you want to 
hear and plav away. 



you to turn local control off, you 
should do so when using X-oR. 
This separates the keyboard from 
the sound -generating circuitry of 
your synth, and will help prevent 
Ml Dl feedback loops among other 
things. If things do get crazy for 
some reason, X-oR pro\'ides a 
Panic command, that will send a 
notes-off message forall 1 28 MIDI 
notes, zero the pitch wheel, and 
turn off the sustain pedal. This 
shou Id la ke c,i re of a 1 1 b u t the most 
\'ilc forms of MIDI Madness. 




X-oR is a full-featured universal system-exclusive editor and 
librarian. 



X-oR likes to maintain con- 
trol over all aspects of its work 
and, to that end, filters out pro- 
gram changes as part of its default 
setup. You can override this, but 
you're advised to leave it alcine 
unless you have a specific reason 
for wanting it otherwise. A simi- 
lar caxeaf applies when setting 
local control on vour master key- 
board. If your main axe allows

You can have 10 bonks open in X-oR at one time. These can 
be sounds, tuning tables, or any other data type. 



Five Columns of Info 
In Performance Window 

The basic X-oR screen dis- 
plays the Performance window. 
X-oR presents all the modules you 
defined in the instrument setup 
here line by line with information 
abtiu t each module. There are five 
columns that show the Status/ 
Receive Channel, the Instrument, 
the Module, the Patch, and the 
Patch Stiurce. The Status/ Receive 
Channel usually displays the cur- 
rent MIDI channel of the Module. 
The Instrument, Mcxiuleand Pa tch 
columns hold the names of the 
current Instrument (e.g. Korg T- 
3), Module (e.g. Program) and 
Patch (e.g. One World) respec- 
tively. The Patch Source column 
contains either the last name that 
vou sa^'ed the patch under or the 
location in the MIDI device that 
you retrieved the Patch from. Most 
things that happen in X-oR are 
initiated from this window or will 
affect the display in this window. 

You can set up your first Per- 
formance by selecting Get Perfor- 
nrance Patches from the Get/Send 
menu. This will request the cur- 
rent patch from each of your

mable s\vitcher, X-oR will do the 
dirty work for you. If you don't,

cliange is shown in the Perfor- 
mance. The Performance window 
is intended to be a constantly up- 
dated status report of vour MIDI 
system, Whenever a change is 
made to a bank, library, patch, etc., 
it will be reflected in the Perfor- 
mance u'indoiv. 

Where Performances contain 
data from the different synths in 



yoursystem, Banks only hold Data 
Types for a particular synlh. You 
can have 10 Brinks opeti in X-oK at 
one time. These can be sounds, 
tuning tables, or any other data 
type. The storage capacity of the 
instrument determines bank size. 
A DX-7 bank would hold 32 
patches, while a Proteus XR would 
hold 384. You can edit, rearrange, 
rename, or delete individual 
patches from within a Bank as well 
as copy, move or swap patches 



within a tSank or across iiaiiks. 
Clicking on a Patch from a Bank 
loads that Patch into the instru- 
ment. You can traiisferenti re Banks 
to and from your .synth and save 
as many as you have disk space 
for. 

Librariesare similar to Banks, 
yet have differing features and 
capabilities that complement Bank 
functions. Where Banks can hold 
only one bank's ivorth of informa- 
tion. Library size is limited only by 
disk space. Ban ks ca n hold as man V 
data types as there are in an in- 
stru menf, where Libraries can on ly 
handle one type per Library (eg. 
patches, master settings, tuning 
tables, etc.). Libraries can be used 
as a type of database, with a vari- 
ety of sort and search parameters 
possible. Unlike Banks, Libraries 
do iTOt automatically load their 
data into the computer. Only the 
directory is loaded until you start 
selecting patches. 

X-oR will not let you save 
duplicates to a Library, It checks 
the name of any new sound you 
wish to add against the current 



scribe a sound. Attaching a set of 
kcy^vords (e.g. string, \'iola, bright, 
fast attack, etc.), to sotinds in vour 
String Library wall distinguish 
String 1 from String 2 far better 
that! a list of generic names and 
numbers would. There's room for 
a unique Coinmeiit for each cntrv 
as well. And, if you aren't happy 
with the pro\'ided keyivords, you 
can edit the Keynvords.TXT file 
with your favorite text editor and 
make up kev;vords of \'our ou'n. 
The Patch Editing features are 
comprehensive and easy tn un- 
derstand. Each Profile contains all 
information required to set up a 
graphic image of the paratiieters 
of any supported piece of iVUDI 
equipment. The image is made up 
of three special types of Parameter 
Objects. Sliders are used to edit 
continuous controllet^. You can 
use Sliders to control le\'el and 
direction type parameters (e.g. 
volume of oscillator 1, panning, 
etc.). Text Bo.xes aliow you to se- 
lect from a list of labels that de- 
scribe a setting on your synth.

Library patches. If it finds a dupli- 
cate, it tells you that the Patch al- 
ready exist.s in the Library. If the 
names are the same, but the data 
differs, X-oR w\\[ ask you whether 
you want to replace the existing 
Patch, add the new entry or cancel. 
This greatly simplifies what can 
be a very time-consuming process. 
Another neat feature of X- 
oR's Libraries is the Library Patch 
Information requester. This pro- 
vides a means of identifying 
sounds by choosing characteris- 
tics from a series of criteria — called 
keywords — that you feel best de- 



\vave5hapes, modes or on/off 
switches. Envelope graphs adjust 
the le\els and positions of enve- 
lope generators. Finally, envelope 
generators are what "shape" the 
sound. These can control the 
instrument's pitch, filtering, and 
amplification characteristics.X-oR 
lets vou change the attack, decay, 
sustain, release and other aspects 
of these characteristics by grab- 
bing a point on the envelope and 
pulling it to a new position. You 
can hear the changes immediately 
either through mouse auditioning 
or playing your master synlh key-

Paste over a Patch 

X-oIi lets you Transplant a 
whole section of a Patch and use it 
as the basis for other Patches. You 
could also paste a section over 
another Patch. In this way you 
could, for example, add the attack 
characteristics of your favorite 
trumpet patch to a fviller-bodied 
brass patch that didn't ha^-e 
enough bite at the beginning of the 
sound. You can Transplant a sec- 
tion to every location of a Bank 
with Transplant -> Bank. This 
could give you a Bank of a specific 
set of parameters upon u'hich to 
build individual sounds for the 
Bank. lfyou\vant to duplicate cer- 



or Mingle gradually or randomh'. 
You choose which parameters to 
use and X-oR does the rest. You 
can also mask pnrameter.s. This 
means you can tell X-oR to leave 
certain aspects of the sound alone 
^vhen creating new sounds. Mask- 
ing tuning settings, for example, 
could make a larger percentage of 
the new sounds more immediately 
useful. 

Dr. T's software has always 
made ample provisions for text 
entry and X-oR is no exception. In

BankCommcnts, there jsa Bootup

put notes to yourself about special 
quirks and routines in your svs- 
tern. You won't e\'en need your 
favorite text editor, X-oR lets you 
make vour changes from within 



It's hard to imagine 

anyone wino wouldn't 

profit from X-oR; it does 

everything well. 



tain ch aracteristics of a sou nd , y o u 
can use the Copy Section feature 
of the Edit menu. This will let you 
duplicate envelopes, oscillator 
settings, etc., instead of having to 
recreate these settings from 
scratch. The amount of control you 
have over the parameters of a 
sound is truly staggering. 

One of the most wildly cre- 
ative aspects of X-oR revolve 
around the Blend /Mingle and 
Randomize functions. If you don't 
know exactly what you want to 
create, but you want to try some- 
thing, X-oR lots you create Banks 
of variations based on two selected 
Patches. Blending creates a new 
Patch by averaging the corre- 
sponding parameters on the h\'0 
Patches, while Mingle creates a 
Patch by copying some parameters 
from one Patch and some from the 
second Patch. You can ei ther Blend 



the program. Although you can 
resize the window as large as you 
like, text entry is limited to 19 lines. 

X-oR is also one of the few 
programs I've seen that uses the 
Help key on the Amiga. A Help 
file for any Profile is available by 
highlighting the Profile and hit- 
ting the Help key. This beats 
searching through the manual any 
day. Since most of the tech sup- 
port questions thai Dr. T's receive 
have to do with Profiles, it makes 
good sense to ha\'e the.se help files 
within easy reach. Users encoun- 
tering difficulties should be able 
to head off some of their problems 
by examining these files before 
making that long distance call. 
Sounds like a good dose of pre- 
ventive medicine from the Doctor. 

As nice as X-oR is, there are a 
few areas for improvement. The 
manual could use more graphics

to accompany the text, or a tutorial 
approach that walks the user 
through an explnnntion, pointing 
out what should be on the screen 
and what it means. While there is 
on-screen help for the Profiles, it 
would be nice to have a Help screen 
for the different features and func- 
tions of the program. Not being 
able to open more than one Perfor- 
mance window is puzzling. Tliere 
should he some way to create 
multiple Performances and have 
them available for swapping, edit- 
ing and cotTiparing. X-oR's main 
competition, MIDI Quest, has a 
Database feature, which allows 
you to collect different types of 
data from your synths and store 
them together in one Database. 
You can ha\'e as many of these 
Databases open as you like, lim- 
ited only by system memory. 

X-oR does so many things 
well, it's hard to imagine anyone 
who couldn't profit by its use. A 
lot of thought has gone into the 
program's purpose atid design. To 
ho able to edit and create patches 
and sounds on any piece of MIDI 
equipment you may own, and then 



catalog and arrange the results in a 
variety of ways is an incredible 
amount of power. To have all this 
available from one program on 
your Amiga is even more amaz- 
ing, If vou have a collection of 
dedicated editor/librarians, or, 
worse yet, you don't have any way 
to use your Amiga to edit and 
organizoyour Synth's sounds, you 
owe it to yourself to check out X-

Does the world need vet an- 
other word processor? Do we need 
to keep re-inventing the wheel? 
Maybe. Let's take a look. 

After all, we do have avail- 
able such high-end u'ord proces- 
sor.sas WordPerfect, ProWrite. Pen 
Pat, excellence!, QiiickWrite, Becker 
Text, and KitnlWonl'; — to name 
some. "High end" here can also 
mean costly. 

I'd be interested in knowing 
just how manv users avail them- 
selves of all the features of these 
ivord processors. How many of 
US wri te book-length manuseri pts 
with many different chapters, 
subdivisions of^chnpters, tables of 
contents, indices, graphics, and 
text in a variety of fonts, styles, 
pitch, and variable line spacing? 
If you must have all this power, 
then b\- all means pay the neces- 
sary price. If you don't, there's an 
alternative.

Consider, for instance, one 
of the most recent entries for the 
Amiga platform: Personal Write, 
produced by Cloanto Italia and 
distributed by Centaur Software. 
The list price is below S50, only a 
fraction of most of the word pro- 
cessors listed abine. 

Let's first examine what fea- 
tures Personal Write doesn't have. 
To start with, there is no dictio- 
nary/thesaurus/spell checker 
module. You don't get side-by- 
side printing of columns except 
by establishing tabs. This means 
you ha\'c to know exactly what 
itemsgo on each line. Beyond these 
limitations, you get plenty. 

rW works on any Amiga 
with at least 512K of RAM, is 
AmigaDOS vl.O compatible, and 
can be installed on your hard drive 
with the included "InstallPWrite" 
program. 

Cloanto PostScript Driver 

It ha.s a PostScript dri\'er — a 
feature that many of us look for in 
a word proces.sor — thoiisands of 
combinations of printer param- 
eters to choose from, and a multi- 
strike mode for those of us with 
tired print heads, or threadbareor 
worn-out ribbons. The PW pro- 
gram disk alread)' contains driv- 
ers for the CBM MPS-1000, 
EpsonQ, EpsonXOld, Hewlett- 
Packard LaserJet, and the NEC 
Pinwriter. Other drivers can be 
copied from the Commodore Ex- 
tras Disk using the Commodore 
"InstallPrinter" utility. The 
Cloanto Postscript driver works 
in combination with anv Amiga 
printer driver — from the Alphapro 
101 to the Xerox 4020, 

So much for printers and 
printing, but what about file for- 
mat? you ask. PW can load and 
save text, combining more than 25 
characters sets of the most widely 
used computers. Also files can be 
sa\-ed as Compressed, IFP-nrXT, 
ANSI x3,64, ASCII, Encrypted, 
PRINT ANSI, and PRINT ASCII. 
Different IFF graphic formats can 
be read and displayed on the main 
screen of PVV, in up toeightcolors. 

What if you generally write 
your documents in, say, German? 
This is not a problem with I'W; 



three requesters allow vou to se- 
lect different combinations of 
document, Liscr interface, and 
keyboard language from German, 
Italian, French, Spanish, Duich, or 
Other (user customized). 

Like its more expensive 
counterparts, PW is capable of 
search and replace, cul-copv- 
pasto, mail merge, and automatic 
save. Of course, it can also print 
bold, normal, italics, underlined, 
and proportional with automatic 
justification. It lets you name pitch, 
font, and line spacing — ^in frac- 
tions of an inch or in centimeters. 
And if you're a busy person on 
your Amiga, a print spooler can 
print long documents in the back- 
ground whileyou crunch numbers 
in your favorite spreadsheet or 
input vital statistics in your data- 
base. 

Sorting on Different Fields 

PW has a block sort function, 
^^'hereby i t rea rrangos the con ten Is 
of a block to place lines in alpha- 
numeric order, ascending or de- 
scending. Here is an example: 

..\imee (789) 123-llM 
Jeff 14561 789-45*7 
Tim 11231 456-12M 
Tmc! tU~) MS-.1797 

This is a block beginning with 
a name in the first column and a 
telephone number in cokimn I.'i. 
The block can be marked from the 
first character of the first line — to 
column 25 in the fourth line. The 
sort in this case proceeds by the 
name in the first column; if twoor 
more names arc the .same, then the 
telephone number is examined to 
determine which takes prece- 
dence. 

If the sort were to made ac- 
cording to the telephone number, 
the block would be marked from 
column 15 of the first line to col- 
umn 25 of the last line. If in this 
case two or more telephone ni.mi- 
bers were the same — members of 
the same household or colleagues 
in the same office, for instance — 
then PW ivould look at the names 
to accomplish the sort, or order. 

PWhasanother function that

Directory Opus 

Opus Is Not Just a Penguin Anymore!

An Outlandish Mix-up 

Tlie original name for 
DirectoryOpus was simply Opus. 
I think my letter to Jonathan Pot- 
ter, the author of both, may have 
had something to do with thename 
change. You see, I wrote to him in 
Australia the day after 1 discov-

days v^•hon you could not bu)' 
Opus in the Slates. A friend of a 
friend, so the stor)' goes, is a com- 
puter bulletin board freak who 
cruises the boards ever\' night for 
cool files. His tastes run toward 
animations and cartoons, so when 
he saw a file called simply "opus," 
naturally he thought what any 
American who reads the Sunday 
comics would think: "Oh, bo}', a 
Bloom County animation!" Who 
could resist downloading an ani-

mntion of our favorite demented, 
whistling-impaired penguin. 
Opus? So he yielded, and disco\'- 
ered it was just another directory 
utility. ..ho-huni... until he tried it 
out, and found it was as much fun 
as the original Opus, and just as 
endearing. Even without having 
any documentation for Opus, all 
of the people in our Amiga club 
agreed that Opus was much better 
and easier to use than the direc- 
tory utilities we had been using- 
They appointed me to write to 
Australia and get some docu- 
mented, registered copiesof Opus. 
Hence my letter in ivhich, perha ps 
I was a little too candid in telling 
Mr. Potter about the mix-up of his

Inside the configuration program, an example of one way to configure Opus to run on ARexx 
program with on input/output window. Ttie script file 'Envelope-PSPrinfer' in the Sys;s directory has 
its script bit set (using the Opus PROTECT gadget) and contains the command (Rx E.rexx) necessary 
to launch the ARexx macro "E.rexx" which actually prints the envelope. 



copy from my favorite dealer. The 
street price is only S35, and 
DirectoryOpus is right up there 
with .A.Rexx on the scale of "bang 
for your buck." You are probably 
thinking by now, how can anyone 
get excited over a directory util- 
ity? How boring! You, my friend, 
have never tried DirectoryOpus. 
Mv outlandish enthusiasm is not 
because of the name, cither; it is 
because of wliat 1 can do uith 
Opus. (I'mgoingback to using the 
old name, Opus; I'm more fond of 
it. I will expect you not to think of 
a penguin any more during the 
rest of this re\'iew.) 

A Paragon of User 
Friendliness 

Opus is so intuitive that you 
can use it ^vithout the manual at 
all. 1 did so until I could obtain a 
registered commercial copy and 
had no trouble at all doing the 
standard things in all directory 
utilities: copying files, making di- 
rectories, deleting files, reading 
text files, showing pictures, and so 
on. I knew that getting a proper 
copy with documentation was 
going to unlock even more possi- 
bilities, because from what I could 
see, the creative details ran deep. 
The updated version did not dis- 
appoint me. Tlie improved \-er- 
sion 3.22 of DirectoryOpus is a 
wonder of ingeniousness, a para- 
gon of user friendliness. 1 hardly 
know where to begin. The screen 
layout makes an efficient use of 
the space, At the top it has the 
usual menu bar, which is fully 
userconfigurableand comes with 
several useful default settings, all 
of which can be modified. There 
areplaces for 100 menu items. The 
main screen is composed of three 
information bars where memory, 
diskspace, and soon are displayed 
dynamicallv; one bar for general 
information, and one above each 
window displaying the directory. 
Clicking on the far right of the top 
bar acts as a front-to-bnck gadget, 
but there is no visual indication of 
this. It's so standard that it hardly 
needsa gadget, Below the top bars 
are two side-by-side windows to 
display the files and directories- 
One window or the other is active 
and becomes the source window, 
while the other inactive window

is the destinntton window. A 
mouse click or pressing the spnce 
bar toggles between active win- 
dows. All Opus ctunmands are 
performed according to the active 
window and \vliat tiles or directo- 
ries are selected there. You can 
select mulfiple files by clicking and 
dragging, using the ALL or the 
NONE gadgets, or select them one 
at a time with a single click. Click- 
ing them again after the double 
click time limit deselects each file. 
You can sci'oil around vertically 
and horizontally bv: Clicking and 
holding the Right Mouse Button 
(the position of the pointer in the 
window determines the direction 
of the scroll): Using the keyboard

dow are the scrolls and arrows to 
dn the vertical moves in the direc- 
tory. If you type a character, the 
windo\v scrolls to display the first 
entry beginning with that letter. If 
you type the key shifted, the 
window goes to the first file be- 
ginning with that letter. This is

rectory, which I configured Opus 
to open as a default. You may 
configure both windows to open 
any directory at startup. Below 
the windows are the sliders and 
gadgets to scroll horizontally to 
see datestamps and comments on 
files, and to jump between buff- 
ers. Buffers contain the act!\'C

command line history in the shell, 
except directory windows instead 
of commands are remembered and 
displayed. Hach window can have

ries you've opened! You can jump 
between buffers b^■ using the 
mouse or the keyboard. Yon can 
navigate the most complex direc- 
tory trees with flying ease. Opus 
even has a feature to call up a 
directory tree display in either of 
t he w i nd ovx's, as ivel i as the ability 
to call up all assigned devices or a

This is what 
the main 
screen of 
Opus looks 
like with 
two 

directories 
loaded. 



at the far left, but by clicking there 
with the Right Mouse i3utton, you 
can move through three more 
banks of six drive gadgets and 
back to the original (a total of 24). 

One Hundred Sixty-Eigtit 
Custom Gadgets 

To the right of the six dis- 
played drive gadgets are 42 func- 
tion gadgets, again changeable to 
your heart's desire. A fairly com- 
pletesetof default functionscomes 
installed, so you needn't start cus- 
tomijiing unless you really need 
to. I have enjoyed changing Opus 
as I go. It's so fast and easy, 1 just 
get thought, "That'd be nice to 
have as a menu item or a custom 
gadget," and in a twinkling 1 have 
it. I made ail my CrossDos utilities 
such as formatting, disk copy MS- 
DOS, and soon as new menu i tems 
in the Disk menu that comes al- 
ready configured for AmigaDOS 



torn bar, which displays a clock 
and memory and disk informa- 
tion, will bring up another bank of 
42. You may further assign a sepa- 
rate function to each gadget in 
each bank to be accessed bv click- 
ing with the Right Mouse Button 
instead of the Left MoLise Hutton, 
gi\'ing the whopping total of 168 
custom function gadgets! Each 
gadget or menu item may launch 
anexecutablecommand.anARexx 
program, or an Amiga script file, 
called "batch" in the Opus re- 
quester. If the function is execut- 
able and exterior to Opus and 
needs )'Ou to suppi)' arguments, 
there is an easy way to make the 
function request its arguments in 
a window or to operate directly 
upon the highlighted selected 
filG(s), with or without path names 
attached. You may program the 
requesters to have a custom title 
and a custom prompt, either or 



Keymapping, Configuring 
and Online Help 

Opus has Ltn online help fea- 
ture. You may choose help by 
menu or by tiny gadget. After you 
enter help mode, a message dis- 
plays on the top bar telling you to 
select the function in question, and 
if you do, a help message box is 
displayed in the center of the 
screen with a continue gadget 
which makes the box go away. 
After you finish looking at what 
things do, selecting the help gad- 
get or the menu hcl p a second time 
will exit help. What is really neat, 
howe\'er, is that you can write 
your own help messages for your 
custom gadgets! The help file is in 
the SYS:S directory and making 
vour own entry is as simple as 
loading the file into your editor, 
putting an asterisk * in front of the 
name of your gadget or menu 
function (on a separate line); en-

toring the lines iif help text; dnd 
ending witli n ^ symbol at the end 
of the last line. Your message will 
be displayed exactly like the rest! 
If vou assigned a keyboard short- 
cut to voiir custom frinction, it is 
automatically included in the help 
message box; you never have to 
tvpcthis in! Unlikeordinary saves 
to the configuration, to see your 
new help messages, vou must exit 
and restart the program. 

Opus alknv.s complete 
kevmapping and hot keys (which 
bring up Opus to the front screen 
lirom anywhere), so the combina- 
tions are endless. If you'd like 
something to work another way or 
want to access something ^vith a 
different keyboard shortcut se- 
quence, you can change it. Any 
gadget or menu item may be as- 
signed a keyboard shortcut. One 
of the strongest features of Opus is 
how easy it is to re-configure 
something. You may sa\'eas many 
configuration files as you want, 
also, and load them at anv time in 
a few seconds. The configuration 
files are in binary so they are small 
and fast. To reconfigure, you can 
click on a tiny gadget or use the 
menu command or use the default 
Right-Amiga-[C| shortcut. 

Define Your Own File Types 

The 1-iIe Types configuration 
bears discussion as it is one of the 
features that sets Opus apart from 
the competition. Opus allows you 
to define your own file types as a 
class of fi les. For instance, LH A RC 
archive filesare a file type defined 
in the Opus defaults. ARC and 
ZOO are also defined. There is an 
ARC LIST gadget that uses these 
file types to archive and extract 
automatically. You may select 
multiple filosand then click on the 
ARC LIST gadget with the RMB 
(Right N4ouse Button) to extract 
them. They will be extracted and 
copied to the destination window. 
There is also a faster way to 
decrunch files, thanks to custom 
file types. All you ha\'e to do is 
click on the file in a special way 
and Opus automatically recog- 
nizes the archi\'e method, accord- 
ing to the defined file type and 
proceeds unassisted to extract the 
file and copy it into the destination 
directory ^vindow. What is this 



Opus is so intuitive 

tinat you con use it

special click? Opus calls it .i 
Clickmclick. You click once on the 
file and then once in the destina- 
tion directory and the file is ex- 
tracted and copied there auto- 
matically. Clickmclick works only 
if you click in the destination vvin- 
dow before the time limit on 
double clicks expires. If you are 
slow, you can reset this in your 
system Preferences. For example, 
the active windo\\' is DFO: in which 
you ha\'e placed a d isk of crunched 
files to de-archive, and the desti- 
nation window is RAM:. You click 
on one of the file names in the 
active window and quickly click 
again in the RAM: windoiv. The 
file h'pe is recognized and is auto- 
matically dissolved and copied to 
the RAM: window, prompting you 
when it needs to create directories. 
You may quickly copy anv single 
file from one window to another 
with Clickmclick. It does not mat- 
ter if it is an archived file or not. 



Automatic Archiving, 
Window Swapping, and 
PPMore 

You can archive files by se- 
lecting them and then cl icking LMB 
(Left Mouse Button) on the ARC 
ADD gadget. You may configure 
Opus as to which of the three 
archi\'e programs you want to use 
to archive your files. Clickmclick 
a Iso works in the ba rj ust above the 
directory windows. If you click 
first with the LMB in the active 
window bar and then move to the 
bar abo\e the destination window 
and clickasecond timebeforeyour 
double click time is up, the first 
window is duplicated to the sec- 
ond. If you Clickmclick with the 
RMB, the ivindows su'ap places. 
This feature is handy for mo\'ing 
files up or down a directory tree, 
and for other chores. 1 found this 
feature a little touchy. 1 had to use

it worked properly. I found that in 
the top bars at least, the best re- 
sults came when I modified the 
official Clickmclick technique to a 
rapid double click in the first win- 
dow and then a single click within 
the time limit in the second win- 
dow. This gave me better accuracy 
than the standard Clickmclick. Of 
course this modification in tech- 
nique won't work in the case of 
extracting files, because a double 
click on any file will start some 
process going, either to read the 
file, or extract it or play it or what- 
e\'er, depending on what its file 
type definition is. 

The defaults come Avith a 
wildcard * to match any file so at 
the yery least, Opu.s will "smart 
read" the file if you double click it: 
If it is an executabio, Opus will 
read it and display in HEX, or read 
it as ASCII if its text. Opus is hard 
coded to read text files crunched 
by PowerPacker, too, although this 
is not mentioned in the manual. 
Unfortimatelv, vou may not print 
PowerPacked files normally, as 
they will look like gibberish. For- 
tunately, Opus uses PPMore to 
read files, and it contains a facihty 
to print them as well, but only 
through Preferences. The upshot 
of using FileTypes and the custom 
gadgetsand menu featuresof Opus 
is that it is possible and feasible to 
laimch any or al! of vour Amiga 
applications from Opus and even 
do away with WorkBench if vou 
want. I am customi/^ing more and 
more gadgets to run programs 
from Opus. The reason I am so 
excited about a more directory 
utility is that in any working day, 
I spend hours dealing with vari- 
ous files and prograins so the at- 
tracti\'cness of the Opus interface 
keeps me happiK' chugging along 
with a minimum of el'fort. I can 
make Opus look any way 1 want, 
even to changing the color of the 
sliders and the positions of the 
arrou' gadgets. The pou'er of the 
program makes chores that used 
to be tedious (like de-crunching 
archives) easy and fun.

Resource macro disassembler — NEW VERSION! 

Resource V5 is an intelligent interactive disassembler (or tfie Amiga programmer. Resource V5 is blindingly fast, disassembling literally 
hundreds of thousands of lines per minute from executable files, binary files, disk tracks, or directly from memory. Full use is made of the Amiga 
windowing environment, and there are over 900 functions to make disassembling code easier and more thorough than its ever been. 

Virtually all V2.0 Amiga symbol bases are available at the touch of a key. In addition, you may create your own symbol bases. Base-relative 
addressing, using any address register, is supported for disassembling compiled programs. All Amiga hunk types are supported for code scan. 

Resource V5 runs on any 680x0 CPU, but automatically detects the presence of an 020/030 CPU and runs faster routines if possible. 
Resource V5 understands 68030 instructions and supports the new M68000 Family assembly language syntax as specified by fVlotorola for the 
new addressing modes used on the 020/030 processors. Resource V5 and Macro68 are among the few Amiga programs now available that 
provide this support. Old syntax is also supported as a user option. 

An all new online help facility featuring hypertext word indexing is included. This enables you to get in-depth help about any function at the touch 
of a key! Resource V5 includes a new, completely rewritten manual featuring two tutorials on disasssembly, and comprehensive instructions for 
utilizing the power in Resource V5. 

Resource V5 will enable you to explore the Amiga. Find out how your favorite program works. Fix bugs in executables. Examine your own 
compiled code. 

"If you're serious about disassembling code, look no furtherl" 

Resource V5 requires VI .3 or later of the Amiga OS, and at feast 1 megabyte of ram. Resource V5 supercedes all previous versions.

Macro68 macroassembler — NEW VERSION! ^ $30 off! 

H/lacro68 is the most powerful assembler for the entire line of Amiga personal computers. 

Macro68 supports the entire f^otorola K/168000 Family including the MC68030 and iyC68040 CPUs, MC68881 and IVIG68882 FPUs and 
MC68851 MfiflU. The Amiga Copper is aiso supported, eliminating the need for tedious hand coding of 'Copper Lists', 

This fast, multi-pass assembler supports the new K/lotorola ft/168000 Family assembly language syntax, and comes with a utility to convert 
old-style syntax source code painlessly. The new syntax was developed by fVlolorola specifically to support the addressing capabilities of the 
new generation of CPUs. Old-style syntax is also supported, at slightly reduced assembly speeds. 

t\/lost features of Macro68 are (imited only by available memory. It also boasts macro power unparalleled in products of this class. There are 
many new and innovative assembler directives. For instance, a special structure offset directive assures maximum compatibility with the Amiga's 
interface conventions. A frame offset directive makes dealing with stack storage easy. Both forward and backward branches, as well as many 
other instructions, may be optimized by a sophisticated N-pass optimizer. Full listing control, including cross-referenced listings, is standard, A 
user-accessible file provides the ability to customize directives and run-time messages from the assembler. 

MacroSS is fully re-entrant, and may be made resident. An AREXX''- interface provides "real-time" communication with the editor of your choice. A 
number of directives enable Macro68 to communicate with AmigaDos''-'. External programs may be invoked on either pass, and the results interpreted. 
Possibly the most unique feature of Macro68 is the use of a shared-library, which allows resident preassembled include files for incredibly fast assemblies. 

IVIacro68 is compatible with the directives used by most popular assemblers. Output file formats include executable object, linkable object, 
binary image, and Motorola S records. Macro68 requires at least 1 meg of memory.

nil yt'iir other directory prtigi'iims 
once you get this one. 1 can't ini<ig- 
ine Amiga life without Opus. I 
recommend it highly. This is iiil 
imperfect world, howe\'er, and 
groat as Opus is, I found Iwo bugs. 
The first bug is that you <ire sup- 
posed to be able to select niultiple 
files by clicking and dragging on 
them in the directory window.This 
feature does not work if yon hn\'o 
ctmfigured Opus to open on ti 
WorkBench screen; it works only 
in the custom screen mode. I ivas 
LisingSvsteml.O on an Amiga 3000, 
but Opus is advertised to be com- 
patible with SysteiTi2.0, so this is 
clearly a bug that needs fixing. The 
other bug is in the ARexx Inter- 
face. The SELECTFILE command 
on page 10-13 of the manual does 
not work properly. It does not se- 
lect.! file by name as it is supptisod 
to. It does, howeycr, deselect a file 
by name, but the {sclectstatel (dis- 
play] options do not ftmction, and 
there is no information in the 
ARexx RESULT variable as 
claimed. This is an important cont- 
mand, and needs to work prop- 
erly. Fortunately, 1 found a 
workaround. You may use the 
SELECT comtiiand (page 10-H), 
which isdesigned to find a pattern 
and select the file based upon the 
pattern. If you simply use the en- 
tire filename as the pattern you 
may select a file successfully, but 
you are still unable to select the 
display state as not updated, and 
there is no content to the RETURN 
\'ariable. 

Conclusions 

A,s for flaws, there is a minor 
one. Opus is a big prograni {Opus 
and support files/programs take 
upabout3S0,t»0 bytes) and it takes 
a longer time to load than other 
directory utilities. Size is not a 
problem unless you are on a flopp)' 
disk based system with low 
meniory. If this is the case, you 
niav want to consider size before 
you choose Opus. Since you can 
start Opus iconified from your 
startup-sequence, and since it 
icunifies/de-iconifics bv gadget, 
menu, or hot-keys, the slower 
loading is not really much of a 



problem. I don't notice it at all on 
an A-300Q but on an A-2(101l, (he 
delay in loading is noticeable, but 
not obnoxious. 1 just never quit 
Opus until ! turn off my maclnine. 
When I'm not using it, I iconify it. 
It's a welcome little memory 
minder and clock on my 
WorkBench window. 

Last, but not least — some 
.'\miga program de\'elopers seem 
to imagine it is least — is the 
manual. The DireclorvOpus 
manual by Jonathan Potter is well 
written, spiral bound, organized 
as well as the program is, and in- 
dexed in a way that would vv'arni 
the heart of Marian the Librarian. 
The explanations in the .ARexx In- 
terface are a little lean on informa- 
tion and examples, hoivever. 
DirectorvOpus is indeed a neces- 
sity for anyone who owiis an 
Amiga. Its thougiitful and inge- 
nious interface, the attentiim to 
detail and configurability, and its 
internal functions with added 
ARexx power make it satisfying 
and fun to use it every day. 1 in- 
tend to write another letter to Mr. 
Potter. 1 ha\e an idea for his next 
programming masterpiece. 1 want 
him to make an auto-trace strtic- 
tured drawing package, aiid I'm 
hoping he will let me select the 
name this time. I'd like to call it 
"BILL the CAD." ,^q.

MIDI 



While X-oR is not unique in Ihu 
Amiga community, it is a 
WL'Icivme nddition. It's mnin com- 
petitor, MID! Qifi'st, lins bufn 
nround a bit longeron the Amiga, 
and provides some unique fea- 
tures and a slightly dit'ferent ap- 
proach to editing and cataloging 
patches. Let's look at some of the 
pluses and minuses of each, 

Both X-oR and MIDI Quest 
use mouse auditioning. Profile/ 
driver help, switcher control, etc. 
Both companies provide excellent 
technical support. Both products 
can control your MIDI switcher to 
send sounds back and forth be- 
tween your MIDI gear and your 
Amiga. X-oR requires you to cre- 
ate programs on your switcher in 
order to use it. You can't just stay 
in your master switcher setup and 
have X-oR send info back and 
forth. MIDI Quest, on the other 
hand, will work quite nicely with 
your default setup, assuming your 
ma in switcher program allows for 
bi-directional communication. 
This means having the ability to 
merge data from, say, you r master 
controller and your Amiga to all 
your synths connected to the 
switcher. The X-oR manual warns 
against these merging types of 
setups specifically. .MIDI Quest has 
an integrated sequence player, 
where X-oK requires a Dr. T se- 
quencer and MPE. MIDI Quest's 
Database feature is analogous to 
X-oR's Performance. You can ' t ed i t 
a MIDI Quest Database by chang- 
ing patches on your instrument, 
as you can with X-oR. However, 
MIDI Quest allows multiple 
Databases to be open at one time 
and allows transfer of data be- 
tu'oen Databases. MIDI Quest can 
only let you edit Patches stored 
directly in a Database. This means 
that if you have a Bank of sounds 
as part of a Database, you cannot 
retrieve or edit a particular Patch 
in the Bank. MIDI Quest has notes, 
chords, and arpeggio mouse ati- 
ditioning, while X-oR allows you 
to send glissando, pitch bend, and 
controller messages over MIDI. 
MIDI Quest allows you to have as 
many iipen Banks as you have 



memory for. MIDI Quest can save 
SysEx files as standard Midifiles, 
although Blue Ribbon 
Soundworks is the only company 
I know of in the Amiga market 
e\-en considering adding this fea- 
ture to their sequencers. MTD! 
Quest is always quick with data 
transfers, where X'oR requires vou 
to experiment with transfer rate 
settings to discover the optimum 
rate for vour system. MIDI Quest 
lets you modify an already exist- 
ing driver or create a new one 
from scratch. SoundQuest has a 
companion program to MIDI 
Quest called TechQuest, which lets 
you create yourown templa tes for 
your MIDI gear. This is great for 
those of us with older, less main- 
stream MIDI equipment and for 
those with the latest stuff hot off 
the press. If you've got the chops, 
you'd never again have to wait for 
someone else to wri te a d river and 
template with MIDI Quest and 
TechQuest. 

With all these things in 
MIDI Quest's favor, you might 
wonder ivhy you'd even consider 
using X-oR. In many ways MIDI 
Quest is the more powerful and 
comprehensive program, but it is 
a difficult beast to master. MIDI 
Quest can appear to be very 
complicated and buggy, and the 
manual isn't as helpful as it should 
be. I've left sessions with MIDI 
Quest in a daze, trying to under- 
stand the concepts and capabili- 
ties of the program. ! can't empha- 
size strongly enough how impor- 
tant a good manual can be. In fact, 
I learned more about how to use 
MIDI Quest from working with X- 
oR and its manual! This single 
reason is enough for me to rec- 
ommend X-oR to all but the most 
technically proficient and de- 
manding MIDI user. 

(Press relaise: MIDI Quest 1.1 
is curreiithi in the final stiigcs ofdc- 
Vi<lci>iiicut nnd tt'slinn. l^ic-rcUvH- 
copies offlw manual arc a significant 
iiiipWL'cnit'nt over itriviouf versions. > 

There are other reasons to 
consider X-oR. Setup is much 
smoother and less cryptic. X-oK 
has trtie da tabase type functions — 



MIDI Quest or 
X-oR— 

Which is better for you? 

by Rick Manasa 



search by name, date, etc. — in its 
libraries. The program just seems 
more friendly to the average user 
inlayoutand design, as well as the 
aforementioned manual. For 
many years. Dr. T was the Amiga 
MIDI software company, and 
many Amiga music enthusiasts 
have more than one of The Good 
Doctor's programs in their MIDI 
arsenal. If you are familiar with 
any of the other Dr. T's products, 
you'll be right at home with theX- 
oR interface and design. This can 
help level out the learrsing cun'e 
considerably. 

If there was an easy way to 
transferdata between .MIDI Quest 
and X-oR, I'd have both programs 
up and running all the time. 
Somewhere down the road, some- 
one will come up with a standard 
SysEx format, not unlike the 
MidiFile format for sequences. 
Imagine being able to have both 
X-oRand MIDI Quest up and run- 
ning, swapping libraries and 



banks back and forth, taking ad- 
vantage of X-oR's automatic bank 
loading and search functions, and 
MIDI Quest integrated sequence 
player and multiple mouse audi- 
tioning, all at the same time! This 
would let you use each program's 
strengths to organi/o your sounds 
and setups, without limiting you 
to one programmer's vision of how 
that can be done. A worthy project 
for the International MIDI Asso- 
ciation. Howsabout it, guys?

40/4 Magnum 



/ji/ Miitl Dmbick 



I recently lind the opportu- 
nity to evalunte the CSA 40/4 
.Magnum accelenitor uard for the 
Amiga 2000 series. The card uses a 
Motorola 68040 Cr'U running at 
25MHz. The 40/4 MaRUum is 
rated by CSA at 20 Mll'S (million 
instriictitms per second) with a 
built-in math co-processor rated 
at 3.5 MFLOPS {millions of float- 
ing point operations per second). 
Compared tomv Amiga 3000 with 
the Commodore-supplied 68030 



CPU and 68882 math co-proces- 
sor running at 25MHz, I calcu- 
lated that the040card easily ran at 
least twice, almost three times, as 
fast as my Amiga 3000 u-hen per- 
forming ray-tracing and other 
nLimber-criinching tasks. 

Designed to make the A m i ga 
competitive with high-end 3-D 
graphics and animation systems, 
CSA claims that the 40/4 Mag- 
num has nearly 70 percent of the 
speed of a base, single-CPU RISC 




workstation. The significance of 
this claim is the ahilitv for an fi8040 
Amiga equipped with a Toaster or 
other frame buffer to produce 
broadcast-quality images with 
comparable rendering times. Al.so, 
an Amiga 2000 equipped with the 
40/4 Magnum costs substantially 
less to purchase than other high- 
end computer graphic systems. 
Such a combination of perfor- 
mance versus cost should pro\-e 
to be \'cry attractive to companies 
producing 3-D graphics and ani- 
mations. 

The 40/4 Magnum works 
with an Aniiga 2000 or 2500 and 
requires version 2.0 of the operat- 
ing system. The card has 1MB of 
burstabic (zero wait state) 32-bit 
Static KAM,a fast SCSI hard drive 
controller, a parallel port and two 
{RS232 and RS422) serial ports all 
using the 20 MIP en\'ironmen( of 
the 68040 CPU. Four, eight, twelve 
or sixteen megabytes of dynamic 
RAM using 4MB 32-bit SIMM 
modules can be readily used, with 
the potential for 64 or even 128MB 
of memory. Programs that a re run 
from the Static RAM will see a 
large improvement in speed as 
well.

In order to perform a reason- 
ably scientific evaluation of the 
040 against my Amiga 3000, 1 ran 
each test at least three times for 
accuracy. While three times may 
not be statistically significant, the 
chances for either misreading a 
numfier or accidentally running 
the same task differently on both 
machines should be non-existent. 
Unfortunatelv, because the 40/4 
Magnum wouldn't work with any 
of the hard drives that 1 had avail- 
able, and because I coutd only test 
the card for three days before it 
had to be shipped back, I didn't 
have the opportunity to evaluate 
the Magnum with programs such 
as Caligiiri Bnimicafl or Imagine. 1 
did, however, use the ray tracer 
DKBTmcc, Di'hixfPimit IV, Digi- 
Vk'w 4.0, Art Dqnnlrufiil Pwfrf- 
iioiinl, and a Mandelbrot fractal 
generator. Perhaps the most sig- 
nificant program used was 
Dlin/ftnih' Tiiiiw, version 1.1 by 
Mike Konnola of Tinland, 
Dhrystone is an accurate and 
wide!}' recognized program de- 
signed to measure a computer's 
performance against other plat- 
forms. Originally created for the 
PC and UNIX market, the version 
that I used compared tlie Mag- 
num not only to the Amiga 500 
and 3000 but also to 386-SX and 
386-DX CPUs. 

One of the parameters to be 
set when rimning Dhrystone is 
the number of loops that the pro- 
gram should perform. 1 tried the 
suggested minimum of 30,000 
loops f i rst, then 1 00,000 loops, then 
200,000 loops, 500,000 loops, and 
fi na lly 1 ,000,000 loops just to be on 
thesafesidc. 1 haveincludedsome 
of the test results in an accompa- 
n\'ing chart. Verv briefly, com- 
pared to an Amiga 3000 with a 
68030 running at 25 MHz, the 40/ 
4 Magnum tested 3.94 times as 
fast. Compared to an Amiga 2000 
with a 2620 accelerator card the 
Magnum runs about 7,94 times as 
fast, and compared to an Amiga 
500 with the stock CPU, the Mag- 
num clocks as 24,34 times as fast. 



34 Amazing Computisg 



As iritervsting an lliost; re- 
sults vvL'iL', lliL' ultimate test wns to 
run the same program perfcirm- 
ing an identical task on botFi my 
Amiga 3000 and the Magnum- 
equipped 2000. Knowing that ra\'- 
tracing software invoK'es some 
serious number criuiciiing and 
would be a fair test for both ma- 
chines, 1 created <i large red 
wooden ball i\ith one light sotirce 
rendered as a I lAM image using 
DK!5trace. While the red sphere 
required three and a half minutes 
to he fuilv rendered on the 3000, it 
required only 1:42 on the 40/4 
Magnum, less than half the time. 

Impressed bv the results, ! 
next created a 60-frame animation 
using the dolphin brush included 
withDeluxePaint IV. Porall of the 



frames. The 030 required 2:33 
while the 040 required only 49 
seconds, about one-third of the 
time. 

Another test that i ran used 
Art Department Professional. 
Applying the blur effect to the 
sample GIF image included with 
the program using a cen ter weigh t 
of one and a threshold of eight 
took 12 seconds with the 030 and 
just under five seconds with the 
040. The test results with Digi- 
View (addingred toaHAM image 
and converting it to Dynamic 
mode) and generating a complex 
fractal pattern over and over were 
similar, with about a t^^'0 to three 
times performance increase in 
rendering or processing time us- 
ing the 40/4 Magnum. 



The 040 card easily ran at 
least twice, almost three 
times, as fast as my 3000. 



numerous tests that I ran with 
DPaint IV, the brush always began 
from an off-screen position and 
landed in the \ery center of the 
screen when the animation was 
completed. I first doubled the size 
of the dolphin brush and then set 
the move requester for full 360 
degree spins in both the Y and Z 
axes. Using a high-resohttioii 
screen with ma.\imum overscan 
and a 16-color palette, I was disap- 
pointed with the initial results. 
There was only an eight-second 
difference in rendering time be- 
tween the two machines — 3:38 for 
the 030 and 3:30 for the 040. llow- 
e\'er, when ! ran the same anima- 
tion again with full anti-aliasing, 
the results were truly incredible, 
taking 50 minutes for the 030- 
equipped machine and only 20 
minutes for the 040. The results 
were comparable when perform- 
ing the same animation but in 
PiA.M mode and onh' for 13 



If you perform applications 
\\'here ray-tracing, .3-D graphics 
and animationsare commonplace, 
then consider buying the CSA 40/ 
4 Magnum. While expensive with 
a list price of S3995, the increased 
product!\'it\' from shorter render- 
ing times plus the potential for 
new clients and hence more busi- 
ness will soon pay off. Special

Secretary 



bi/ Chuck linitdonis 



Do you miss appointments? 
Do you forget important dates? 
Do you hn\'e trouble finding phone 
numbers when vou need to talk to 
someone? If so. Expert Seri'ices' 
package SaTi'fiin^mightbe foryou. 
Secretary is a package that is in- 
tended to convert your Amiga into 
a personal secretary. No, your 
Amiga will not answeryour phone 
and greet your clients, but it will 
keep track of all of your appoint- 
ments, organize your phone da- 
tabase, and allow you to organize 
your to-do list in a convenient and 
efficient manner. 

The hea rt of the system is the 
scheduling module. The schedul- 
ing module will allow you to keep 
track of all of your appointments, 
and your to-do list. Tlie main dis- 
play screen is divided into four 
areas. These areas are: Calendar, 
Daily Schedule, To-Do List, and 
Controls Area. The controls area 
contains a series of gadgets that 
provides the interface to the sys- 
tem. The to-do list will be covered 



later in this article. The daily 
schedule portion of the screen 
outlines the events for the current 
day. The da y is blocked ou t in to 26 
half hour blocks. When an ap 
pointmenf is scheduled, its title is 
displayed in theappropriatebkx'k. 
If anappointment is scheduled for 
longer than a half-hour, it must be 
reflected in more than one block. 
The system provides an easy 
method to replicate appointments 
from one half hour block to the 
next time period. Ii\'ery day can be 
tagged with a flag that shows a 
special condition for that day. The 
system provides gadgets that al- 
low the user to tag a day with a 
day flag. This title can indicate 
such things as "Day Off," "Holi- 
day" or "Out of Town " Due to the 
size of the blocks, the length of the 
text for the tags is limited, but it is 
a useful tool. When a da v is tagged 
with a day flag, the title is shown 
on the calendar area. Besides the 
day flags, thecalendararea shows 
the intensity of the scheduling for

that day by shading in a ructangle 
based on the appiiin tmon ts tar tjia t 
day. As each half hour block is 
scheduled, a small block is added 
to the calendar display in the 
relative position of the appoint- 
ment. This indicator allows you to 
tell at a glance how heavily a day is 
scheduled without moviiig to (hiit 



and that item is checked as com- 
pleted. If an item is completed, it 
will he retained with that day's 
information as history. If an item 
is not marked as completed, it will 
be carried over to the next day as 
an open item on the to-do list. This 
feature is much appreciated for

dav. In addition to this indicator 
and the day flag, if a dav has a to- 
do entry scheduled, an asterisk 
will be displayed in that day on 
the calendar. This means the cal- 
endar display gives you a quick 
snapshot of the entire month. 

One of the nicest features of 
Secretary is the to-do entries. To- 
do entries are oriented to a given 
date. If you have to make an im- 
portant phone ca 1 km the 2? th, j us t 
add a to-do entr\- for the 2!itli. 
When that date rolls around, the 
reminder will shovv up in the to- 
do area of the screen. When an 
item that is on the to-do list is 
completed, just place the cursor 
on that item, press Control-flnter

hour day. 

Secretar)' also has a compre- 
hensive search facility. Both the 
to-do and the schedule informa- 
tion can be searched. Any te.xt in 
the system can be searched. If you 
use some thought in how you word 
the entries into the system, you 
can track your activity easily us- 
ing the search facility. The Search 
fiuiction allows you to specify 
whether to search past items or 
fu tu re i tems,and whether to sea rch 
the to-do entries, the schedule en- 
tries, or both. When a search is 
run, a II entries that meet the speci- 
fied criteria, and contain the text 
specified, are sorted by date and 



time and displayed in a scrolling 
window. This huffercan be printed 
for a hard copy reference. 

In addition to the calendar 
and to-do features of Secretary, 
the system also has a phone list 
facility. The phone list system al- 
lows you to store the name of the 
contact, their associated company 
nameand title, twoaddresses, and 
upto fivedifferentphoncnumbers. 
Each of these phone numbers has 
a free-form label that can be used 
to indicate the location of the phone 
number. This will help you keep 
track of the many different types 



w i th or w i thou I ad d resses and can 
be sorted by name or by company 
name. 

For those of you on the go, 
Secretary uMll print a one- or two- 
page schedule summary that is 
formatted to fold tip and fi! in a 
jacket pocket. This summary re- 
flects all activities for the week 
and all to-do entries that are 
scheduled that week. 

Secretary can be iconified to 
place it on the Workbench screen 
when it is not being used. Tlic 
benefit of this feature is that the 
program can be kept loaded at all 




of piione jiumbers that you use 
day to day. The phone book also 
has a find function. Entries can be 
searched on a person's name, or 
on the company name. If multiple 
records meet the search criteria, 
clicking on the button again will 
retrie\'e the next record. With this 
feature, if you need to contact a 
given company but forget who 
your contacts in that company are, 
just enter the name of the com- 
pany in the search field, and then 
page through the available records 
for that company. The phone list 
system also will print mailing la- 
bels for you. If you are talking to a 
contact and decide to mail him 
something, one click on the label 
button and the system will quickly 
print a mailing label. Either ad- 
dress can be used for the label. 
This name and address label also 
can be copied to the Amiga's Clip 
Device to be pasted to another 
program such as a word proces- 
sor. The phone list can be printed 



times so it is convenient when it is 
needed. In this situation, the data 
files need not be read and written 
each time the program is restarted 
and subsequently closed. This 
program is so useful that you will 
want it running on your system all 
the time, so this is an excellent 
feature. I couldn't find fault with 
any of the features in Secretary- It 
is a well thought out and imple- 
mented program. If you tend to 
need someone to organize vour 
appointments, and keep you on 
schedule, don't hire an assistant; 

take a look at Secretary. . „

Deduct that Interest 



A MoxiPlon Template to help frock interest on credit cards. 

by Rick Maiiiifii 




Use MaxiPlan to create ttils easy way to track interest 
and payments on credit cards and loans, 

CREDIT CA RDS OF ABOUT 30 yenrs ago were li kc tcleplioncs at 
the turn of tlic ccntiin'. Most pL'ople ktn.'\v about tliem, but iew people 
owned or used them regularly. Now credit c.irds are like, well, tele- 
phones. It's hard to find someone who doesn't have at least one or two, 
and who doesn't use them regularly. 

Many of us who free lance or who arc solf-employcd use one 
credit card for both business and personal expenses. It's easy enough 
tosit down at the end of the month and determine which expensesarc 
deductible as business expenses and which are not. What is not so easy 
is being able to determine how much of the interest charged is deduct- 
ible. Until a few years ago this wasn't much of a probiem. All interest 
from credit cards was deductible, however the interest accrued . Unfor- 
tunately, 1991 is the last vear that any portion {only 1()'X>) of credit card 
interest ivill be deductible, unless the interest was ciiarged on a 
business expense. After this year, if it's not fora business expense, the 
interest is not deductible. 

So \vhat do vau do? Put FC CALC and vour Amiga to work for 
you. Tills spreadsheet template — and it's little brother FCCALCQUICK 
— started iife as a 15ASIC program on mv C-f4 many years ago. The 
program asks \ou to enter numbers directly from vour credit card 
statement and to do some simple addition. In return, it will painlessly 
assign the correct percentages of the finance charge to vour personal 
and business charges, Dependi ng on how often \'ou use vou r cards for 
business purchases, this can gi\'e you hundrcdsof doUarseach vear in 
interest charge deductions that vou would otherwise not be able to take 
at tax time. 

Let's take a stroll dou'n programjning lane together, to see how 
FC CALC works its magic. All cells that have text or that have 
calculations that FC CALC makes are protected. The only cells that will 
allow you to make input are either completely blank or are ones that 
require some input from the user. 



As the directions on the screen state, the text that asks for your 
entries is in bold. All your ■.'iitries will he in column B, CoUimn A is 
strictly far directions and information. The eel Is that pnn'ide directions 
and information arc in a dark blue. Those that require user input are in 
a lighter blue. Those that display calculations performed by FC CALC 
aresho\vn in red. 

The first entry you will make is in cell Bl<-). Find the New Balance 
on vour statement and put it in here. !ie sure to put the decimal point 
in if your balance includes cents. At this point you should see all the 
ERROR messages in cells B35 — 41 change to some type of numeric 
data. There are formulas in those cells that are looking for data in cell 
Bm (among others). When there is no data there, the subsequent 
formulas find themsehes trying todivide by zero — not a healthy thiiig 
to do. 

Scroll down two lines to cell B21 with vour down cursor key. Ceil 
All asks you to input the Finance Charge (FC). If this is not your first 
statement, you have probably accrued .some interest. Enter it as you did 
the New Balance. You'll notice that the figure you put in B2] is 
duplicated in B41. Not to worry. FC CALC is busy making its calcula- 
tions based on the information it hasat anv gi\-en monrent. As vou put 
in more data tliis and man\' other calculations will change. 

Scroll down two more lines and input the Previous Balance (I^B) 
from your statement in cell B23, Again you'll see FC CALC duplicate 
yourontr\' in a different cell (cell 329), At this point in the process, your 
unpaid balance is your Pre\1ous Balance, because we haven't deducted 
any payments that are listed on vour statement. Let's do that now. 

Cell A25 asks you to enter anv Payments that may ha\'e shoivn up 
on this statement in B25 (\'ou did get that check off last month, didn't 
you?). You'll see the unpaid balance figure in B29 reduced by the 
amount you put in B25, Some credit card issuers also list Credits on 
your statements. These couid be returns, adjustments to vour bill and 
the like. Enter the total Credits in cell B27, If vou ha\e any, the figure 
in B29 will be reduced again by the amount you put into cell B27, 

This brings us to ottr first calculation, the unpaid balance in B2'), 
FC CALC does this and all other calculations for vou. The formula 
looks like this: 

B23-ia25»B271 

The formula says thai the unpaid balance (829) is the Previous 
Balance (B23) minus the Payments (B25} and the Credits (B27), 

Here's a possibility that may happen to you at some point. There's 
a chance that you might end up with a negative ntimber. This could 
happen if you paid more than you owed. Here's an example: Suppose 
you pay off your balance in the same month that you returned that 
electric green and pink three-piece suit your eccentric Uncle Al gave 
you for your birthda\' (you already have three in your cUiset, so he'l! 



Amazi.\g Computing 



iindcrsland). Your credit card statement would shmv you witli a credit 
balnnco, wliicli woLild be expressed ns a negative number. 

Time for more user input. Put tliu New Charges total in cell B31 . 
Some statements split up purchases from cash ad\-ances. To make it 
easy, we've included a separate entry for Advances a t B33. That's all the 
entries needed for Phase 1 . 

Let'ssee what FCCAl.C has done with our fif^ures. Cells B35,B37, 
B39nndB41 hold the results of its calculations based on the in farniatioii 
we've put in so far. We'll take the them one at a time. 

B35 shows the percentage of the total 1-inance Charge that will be 
applied to the New Charges and Advances. Whate\'er figure is show- 
ing in B35 is the result of the following formula: 

(E31 + U33) / Ib:5-E7-.I 

This is as complicated as a formula gets in FC CALC. This one 
calculates the sum of the New Charges and Advances first, and then 
di\-idcs that by the sum of the New Balance minus the Finnnce Charge. 
When you subtract the Finance Charge from the New Balance, you get 
a figure that is the total of the charges made. If you divide that into the 
total of the new Charges and Advances, vou get a percentage that 
represents liow much of the total charges are new. With this figure, it 
is a simple matter to figure out the percentage of the old charges that 
have carried over from your previous statement. Cell B37 calculates 
this with the formula: 



Both B35 and B37are defined as percent format cells. If you think 
of "1" as "100%", you get the idea of what's happeninginB37,FC CALC 
is subtracting the percentage of new charges from 100"'.. of all the 
charges. The resu Itingpcrcentage represents tha tportion of thecharges 
that were made before this statement. Both of these figures are pre- 
sented for your information only. FC CALC doesn't need to display 
them to use them in its calculations. 




Cell B29, your total unpaid balance. 

The figures in B39 and B41 are the actual dollar amounts of the 
total Finance Charge that will be applied toward the New Charges 
(New Charges/Advances) and the Old Charges (unpaid balance). 
These are determined by the formula in B39: 



This formula multiplies the total Finance Charge (B21) by the 
percentage of that total that is for New Charges (B33). This figure is the 
dollar amount of the finance charge that will be applied to new

Cell C109, the non-business totals, 
piu'chascs. The formula in B41: 

subtracts the finance charge on the new purchases (B39) from the total 
finance charge (B21}, This leaves you with the portion of the finance 
charge that will be applied to the old charges. 

So fai' wo'\'e copied the New Balance, Finance Charge, Previous 
Balance, Payments and Credits and Ad\'anccs and Charges figures 
from our monthly statement into FC CALC. For our trouble, FC CALC 
has told us what our unpaid balance is and has also calculated the 
percentages anci dollar amounts of the total finance charge that will be 
applied to old and new credit card purchases. We've entered 7 of the 
y figures FC CALC needs to complete its task. We're almost home. 

Cell A61 asks you to enter the business portion of the unpaid 
balance in cell B6T Cells A45-59 tell you how to do that. The detailed 
instructions are after one thing: How much oflast month's total balance 
was for business expenses? If you used FC CALC last month, Hlis figure 
will be your total business expenses minus any portion of your pay- 
ment that you made toward your business expenses. If this is your first 
month of using your credit card, you won't have a pre\'ious balance at 
all. If this is the first month that you're using FC CALC, but not your 
first month using your credit card, then you'll just have to make an 
educated guess how much of the previous balance was for business 
related expenses. 

After you enter your business tmpaid balance, FC CALC calcu- 
lates the next fi^'e amounts and percentages for you. These are your 
non-business unpaid balance (B63), the percentage of the total unpaid 
balance that is for business (B65) and non-husinoss (B67) use, and the 
dollar amounts of the finance charge on the unpaicH business (B69) and 
non-business (B71) balances. 

Tlie non-business unpaid balance formula in (B63) is simple; 



FC CALC subtracts your business impaid balance from the total 
unpaid balance. The result is your unpaid non-business balance. 
FC CALC calculates the percentages in (B65) and (B67) like so; 

(P,65l ^ B61/B29 (BG7) = 1-EG5 

The percentage of the total unpaid balance tliat is for lousiness use 
is determined by dividing the total unpaid balance (B29) by the 
business impaid balance (B61). The percentage of the total unpaid 
balance that is for non-business use is determined by subtracting the 
business portion from 100'!.. (1-B65).

by B65 gives you the dollnr nmoiint of the finance chars;o that goes 
toward the unpaid business purcliases. Multiplying B41 by B67 pves 
you the dollar amount of the finance charge that goes toward the 
unpaid non-business pinvh.ises. 

The only thing left is to figure out the finance charge percentage 
of the new business and non-businesspurchases and thcdollaramounts. 
The first step is to enter the total of the new business purchases in cell 
B78. Once this is done, FC CALC calculates the remaining percentages 
and dollar amounts and completes its totals. The formula in BS,"> looks 
like this: 

(B31+B33)-378 

The new non-business Charges and Advances figure is deter- 
mined b\ subtracting the new^ business purchases (B7ii) from the total 
new Charges and Advances (B31-hB33). The remaining percentages 
and dollar amounts (B85-91) are analogous to the ones FC CALC 
computed earlier I'or the unpaid business and non business figures 
(B65-71). Here's how they look: 

385 = B78/(B31+B33) 
Bev = B83/(B31+B33) 
BB9 = B85*B39 
B91 = B87*B39 

The b usi ness percentage of the New Charges and Ad \a nces ( B85 ) 
is determined bv di\'iding the total new business Charges and Ad- 
vances (B7S) b)' the total Nevv Charges and Advances (B31+B.33). We 
set up FC CALC to determine the non-business percentage in the same 
wav that it determined thebusiness percentage, just to show a different 
wav of doing it. You'll remember that we subtracted the business 
percentage of the unpaid balance from the total unpnid balance to 
arrive at the percentage of the non- business unpaid balance (1-Bft5). 
Here u'e told FC CALC to di\-idc the new non-business Charges and 
Advances (BS3) by the total New Charges and Advances (B31 -f-B33) to 
determine the non-business percentage of the new Charges and Ad- 
vances (BS7). The dollar figures in B.S9 and i?9l are arrived at by 
multiplying the dollar figure of the finance charge on the New Charges 
and Advances (B39) by the business (B85) and non-business (B87) 
percentages of the new Charges and Adwinces. 

The last set of calculations a re simple addition. The business totals 
add up the unpaid balance (B61), the finance charge on the unpaid 
balance {B6y), the ncnv Charges and Advances (B78) and the finance 
charge on the new Charges and Advances (B8y}. The totals are com- 
puted in cell [3HW with the foilowing formula: 

SOM(B101>B103+B105+B107) 

The non-business totals tallv up similarly. The non-business 
totals add up the unpaid balance (Bfi3), the finance charge on the 
unpaid balance (B71), the new Charges and .^Xdwinces (BK3) and the 
finance charge on the new Charges and Advances (B91), The totals are 
computed in cell C109 with the folloiving formula: 

SUtI (C101+C103+C105+C107 ! 

That's it! If your brain is buzzing from trying to folknv it all, don't 
worrv. iVlv brain hurts from trying to describe it! Just re- read at your 
leisure, whatever \'ou mav have missed Here's a graph that may be 



helpful. 11 sIkuvs the total finance charge as it appears on your state- 
ment and how FC CALC breaks it down into components: 

Total finance charge: 

% of finance charge for 

New Purchases 

% for New Business 

% for New Non-Business 
% of finance charge for 

Unpaid Balance 

% for Old Business 

% for Old Non-business 



FC CALC is m\' one and only foray into prograntming, and v\"hile 
it does what it's supposed to do, there are improvements I'd like to see 
made. It would be nice to ha\'e an addition loop to help calculate the 
unpaid business expense balance at cell B6]. 1 accomplished this in my 
original BASIC program with a FOR ... NEXT loop that totalled figures 
until 1 entered a zero. I'd also like the Return key to ad\-ance you to the 
next cell that requires user entry. 1 think both of these items could be 
handled bv a more experienced spreadsheet jockey lhaii myself. 

The biggest difficult)' J can see is for the first time user who isn't 
starting with a zero balance. You won't know the exact amount of your 
unpaid business balance, so you'll have to guestimate a few of the 
figures on your first go round. After that, you should be in pretty good 
shape. You'll certainh' be in better shape than if \'ou never used the 
program at all. 

While FC CALC isn't fanc\-, it does the job. FC CALCQUICK is an 
even leaner version that fits on one screen. I'd recommend using this 
one after vou become familiar witli FC CALC and don't need all the on 
screen directions. You will save time and money whichever one you 
use, and for a self-employed free lancer, that's important. 

Knovving I'm maximizing the use of my credit card helps take 
some of the sting oLit of the unpaid balance that carries over month after 
month (will 1 ne\er get out of debt?) and the interest that accompanies 
it. FC CALC wilhvork just as well for the second mortgage you've been 
considering — to finance that kitchen remodeling job (non-business) 
and to acquire that new A-3tl00 you'\'e been eyeing down at the local 
computer store — strictl v business use, ofcourselFC CALC has become 
a small but effective tool in my never ending battle i\'ith the budget. If 
you use it at bill paving time, FC CALC can be the same for vou!

A look at presentation packages and authoring programs. 



by Dinv Spitlfr 

^he multimedia boom would not be possible without the 
f availability of "authoring system" and "presentation" pro- 
grams which allow new users to create applications quickly and 
easily. At this point, there are at least 10 such programs and 
more are on the way.

Authoring systems arc to multimedia 
what desktop publishing programs arc to 
printing. By itself, an authoring system is of 
little value, hut used in conjunction with paint 
and animation programs, \ideo and audio 
digitizers, music programs, and word proces- 
sors, it is powerful indeed. An authoring, or 
presentation, svstem provides the tools that 
the user will need to pull all of the inputs 
logetherand structure them. This includes the 
more traditional programmers' tools along U'ith 
the ability to pull text, graphics, animation, 
sound, music and video into the final program. 
.Authoring systems are able to create very in- 
teractive programs through (he use of "hot" 
spots and text input bo.\es. Tliis makes them 
excellent for creating educational and infor- 
mational programs that people who know little 
or nothing about coinpu ters can use unassisted , 
as uell as for programs that allow the user to 
jump around as interest or need dictate rather 
than force him or her to ftillow some pre- 
established format, 

Authoring systems differ from presenta- 
tion systems in the amount of raw program- 
ming power which the\' offer. Presentation 
systems such as Scala or ShowMaker offer an 
arra\' of \-isual tools, \\'hile authoring systems 
such as CanDo and Amiga Vison offer feu'er 
visual tools but more and better programming 
fu nctions. 

The authoring svstem field is essentially 
dominated by five programs: AmigaVision, 
CanDo, The Director Version 2, Hyperbook, 
and FoundaHon. If you believe all you read, all 
five of these programs do essentially the same 
thing, it would seem that the only qLieslion to 
be resolved is, which one does it better. In fact, 
there niay be no overall "best" system, f^ach 
program has its own strengths and weaknesses 
and the five programs are so radically different 
in the way they work that the "best" one is the 
one which suits the project at hand and /or 
matches the personality and needs of the pro- 
grammer. 

The Director (The Right Answers Croup) 
was the firstof these five programs to arriveon 
the scene. From the beginning. The Director

was considered powerful but difficult to use. 
The Director i.s o text-boat'd en\ironment in 
whiclT tlie user creates a "script." .Actually, all 
authoring sy.stems are script generators, but 
other programs insulate the user from script 
creation through the useof a graphic frontend. 
The original Director \vas a straightforward 
text-based script generalor and the few graphic 
tools added to Version 2 do not alter this. Users 
of The Director programs must know exactly 
what they are doing and be able to translate 
their thoughts into a script thai the program 
understands. 

This may be a disadvantage for beginners 
and visually oriented programmers, but the 
rewards are great for those who are willing to 
learn to program w'ithout a lot of graphic frills. 
Director programs are much smaller and tigh ter 
than similar programs generated bv graphic 
authoring .systems and they can do things that 
may be difficult or impossible in graphic pro- 
grams. Since The Director does not carrv the 
weight of a lot of "graphic overhead," it is not 
a memory hog; extra RAM and a hard drive are 
less of a necessity. Lastly, The Director has 
several fLinctions which no other authoring 
s\'stem offers including page-flipping anima- 
tion, the "blit" utility, whieii allows pieces of 
one image to be superimposed on another, 
sprite manipulation, and the ability lo create 
and use special "libraries." 

Director scripts may be "run" at any time 
during the creation process to see how thev 
will look and feel, and completed scripts are 
compiled inlo "films" \vhich are run with the 
freely distributable "projector." 

CanDo (Innovatronics) U'as the second 
program to show up and was the first of the 
four current contenders to offer a graphic envi- 
ronment. CanDo offers an excellent graphic 
front end that is constructed along the lines of 
the "card" strategy. According to this plan, the

programmer creates a series of "cards" and 
then links them by means of pointers which 
allow the user to jump from one card in the 
"stack" or "deck" to another. Several programs 
ha\'cbcen published that use this strategy, but 
CanDo has built-in power and flexibilit\- which 
the competition lacks. 

CanDooffers theusera very well thought- 
out and highh' functional set of grapliic tools to 
use in constructing the cards themselves, cre- 
ating objects on the cards, and arranging the 
various parts of a program. CanDo also offers 
the usera powerful and flexible command set, 
recently expanded in version 1.5. CanDo pro- 
grairuners have created some really impres- 
sive work since the program was introduced 
including, briefly, a disk magazine. 

The bad news, for some, is that, however 
intuitive and easy-to-use its graphic front end 
may be, CanDo forces the programmer to type 
in script sooner or later. Tlie raw power of the 
extensive command set is accessed with the 
keyboard, not the moLise. This means that those 
who shied away from The Director will at least 
initially experience difficulties with CanDo as 
well. 

in order to run well, CanDo prefers a 
"fat" en\'iroment with several megabytes of 
RAM and a hard drive. Programs written with 
CanDo tend to be large, although it is possible 
to create some very impressive programs which 
fit on one floppy disk. CanDo programs may 
be ctistributed either in a large "bound" ver- 
sion which runs with the freely distributable 
"DeckBrowser" or a smaller \'ersion which 
requires CanDo. 

.'Xs ivithThe Director, CanDo offers great 
rewards to those who are u'illing to type lines 
of script, CanDoalso offers some features which 
are not available in other programs including 
the abilit\- to allow users of CanDo "btioks" to

ability to open small workbench screens and 
now offers the ability to open more than one 
window at a time. This means that CanDocan 
be used to create simple utilities as well as 
large, impressive graphics and animation pro- 
grams. In addition, release 1.5 of CanDo offers 
upgraded database abilities as well as the abil- 
ity to access the full range of multimedia de- 
vices, including laser disc players. 

Amiga Vision was laiiched into the mar- 
ketplace in 1 WO as the "official" Commodore 
authoring system for the .'Xmiga. Because of its 
official status, that launch caused a wave of 
excitement in the Amiga community which 
must have made thecompetition a biten^■ious. 
In the initial frenzy, AmigaVision was given 
credit for a number of "firsts" which others 
were already doing, but AmigaVision can le- 
gitimately claim to be the first to offer pro- 
gramming power and reliability in a thor- 
oughly graphicenvironment. The AmigaVision 
user is still writing a "script," but the process is 
so graphic and so intuitive that large blocks of 
code may be written almost exclusively with 
the mouse.

create interactive 

programs through 

the use of "hot" 

spots and text 

input boxes. 

Many new programmers love 
.Amiga Vision's graphiciiiterface. AmigaVision 
was designed around a "flou' chart" strategy 
rather than a "card and stack" approach. This 
flow chart forces the programmer to look at the 
program in the same way that the coniputer 
sees it. Moreover, since nil of the .Amig.i Vision 
programming functions are begun by using 
the mouse to place icons on the flow chart, new 
programmers quickly get to the point uhere 
thev can "see" the program before they begiii 
to write it. This means that it is easier to write 
solid programs and avoid the confusion of 
"spagetti programming."

AmigaVision touches all of the multime- 
dia bases well with a full range of tools lor 
adding art, animation, music, somul files, and 
full motion \ideo to anv presentation. With 
.'\niiga Vision, the "simple slide show" is fun to 
create and easy to ja// up with nifty special 
effects. Advanced programming functions are 
easily accessed as is the fully relational data 
base which is part of the AmigaVision pack- 
age. The .AmigaVision manual is well orga- 
nized and informali\-e, and works well both as 
a tutorial and as a reference book. 

With all of this power and ease of use 
combined with its "official" status, 
.AmigaVision was supposed to completely 
overpower its competition. This has not hap- 
pened for a number of reasons. In the first 
place, there is no way to "bind" or "compile" 
AmigaVision programs for use by computers 
without AmigaVision so that programmers 
write for a limited audience. This was seen as 
a te mpora r\ 1 im i ta tioii when Commodore was 
siiippingAniigaVision with e\erv Amiga sold, 
but a recejil announcement that AmigaVision 
\vill no longer be shipped u'ith low-end ma- 
chines presents a problem. 

In addition, Amiga Vision's impressive 
graphic front end is expensive. The manual 
recommends a minimum of .liVlH of RAM and 
a 4l)MtJ hard disk to do much of anything with 
AmigaVision. A 512K Amiga 500 cannotcreate 
even simple programs. Even with machines 
which are fairly well loaded, "out of memory" 
messages or gurus resulting from fragmented 
chip memory are still pnsssible. 

There are other limitations. AmigaVision 
cannot perform page-flipping animation or 
address specific frames of Anim5 animations 
as The Di rec tor can, nor can it allow the user to 
alter the contents of a displayed text file or 
utilize Anim Brushes as can be done with 
CanDo. AmigaVision will send the text to a 
printer, but on!v one line at a time, while 
CanDo will print an entire document with one 
command. Both Director and CanDo can cre- 
ate programs which "draw" to the screen; 
.AmigaVision does not. The Director's use of 
sprites and "blits" make game-type programs 
possible which are unworkable in

AmigaVision. And, lastly, that totally graphic 
front end becomes a liability in the creation of 
large, complex programs. As mouse clicks 
mount up late into the night, programmers 
begin to long for the ability to just hammer the 
bloody script into the machine and let the 
mouse sit. AmigaVision is an incredible pro- 
gram which clearly demonstrates the power of 
the Amiga in multimedia, but it does riot "wipe 
out" the competition. 

If AmigaVision set a nc^^■ standard for 
ease of use, th.il standard was re-established 
with the Gold Disk's introduction of 
HyperBook. HypcrBtiok seems to be so simple 
to use that it may be the only choice for nevs' 
Amiga owners. The "page and book" organi- 
sation of HyperBook programs resembles the 
"card and deck" strategy found in CanDo, but 
a HyperBook "book" is much more easily cre- 
ated than a CanDo "deck." HyperBook is the 
only program of the four which provides the 
tools necessary to quickly and easily create the 
buttons and "hot" spots which are so vital to 
inleractiveprograms.HypcrBookalsopro\'ides 
a \'ery nice text reader and picture \-iewer, as 
well as a text editor and a set of simple paint 
tools to use in constructing programs. And 
HyperBook does almost everything with re- 
questers "on the current screen" while 
AmigaVision and CanDo often use a series of 
screens to accomplish simple tasks such as 
picture selection or button construction. In 
fact, HyperBook makes the jump from "read" 
mode to "edit" and back so gracefully that the 
transition is hardly noticed. HyperBook offers 
a few convenient options which may be either 
unavailable or difficult to employ in compet- 
ing programs. These features include the abil- 
ity to create "lists" in which each line can be 
assigned an interactive function, "go any-

HyperBook Is small and it is 
fast; the program and its products 
will run on machines ivhich gag 
on CanDo or AmigaVision. It also 
possesses se\'eral nice transition 
effects which the competition does 
not offer yet. 

At first blush, HyperBook 
seems to trade all of this simplic- 
ity for power. Used by itself, 
HyperBook cannot handle ani- 
mation, music or sound files, or 
\-ideo inputs, nor does it offer the higher pro- 
gramming functions which the competition 
has in such profusion, However, these features

and functions are available to HyperBook pro- 
grammers who have access to ARexx. 
HyperBook retains its speed and compactness 
by offering a \'ery good ARexx interface which 
it expects advanced users to employ to do al 1 of 
the fancy stuff. This is both a blessing and a 
curse. While ARexx dependence helps to keep 
the program tight and fast, it also requires the 
programmer to be good at ARexx to get into 
complex applications. Two freelv distributable 
"reader" programscome with HyperBook (one 
large and one is small), but programs which 
incKide ARexx Macros and Commands will 
not run if ARexx is not available. 

In a wav, the most recent arrival on the 
authoring system scene was also one of the 
first. The hot new release from Impulse, Foim- 
dation, is a direct descendant from an earlier 
svstcm called "UltraCard".

Like CanDo, Foundation uses the card 
and stack organizational theme. Foundation 
also lakes the user from graphicprogramniing 
to t)'ped-in script writing pretty quickly. The 
differences arc thnt ['oundation does not re- 
quire the user to wade through a bunch of 
windows to get the script editor, the Founda- 
tion scripting language is closer to real lan- 
guage than most others. Unlike its predeces- 
sor. Foundation appears to be a well designed 
and well written program with <i lot of power. 
Some of the exciting new featuressuch as built- 
in hypertext,automated scripting, background 
objects, and a macro recorder will make Foun- 
dation a strong competitor in the authoring 
system feild. 

Most people who use Amigas extensivoiy 
own and use a batterv of programs which do 
similar things in different ways, Artists nor- 
mally use more than one program for art and 
animation while writers often use different 
word processors for different tasks. As time 
passes and multimedia becomes more a con- 
cept than a buzz word, people will learn that 
there is no one best authoring system for all 
applications. All four current heavyweight 
contenders in the authoring system contest are 
winners. The choice is made both by personal 
preference and by the requirements of the job. 
The pleasant thing is that, at current prices, 
Amiga multimedia programmers can prob- 
ably own all four of the these authoring sys- 
tems for the cost of just one such program on

The 9th Annua 

World of 
Commodore 

Toronto, Canada 



The recent World of Com- 
modoreshow in Toronto, Canndji, 
was a big success. Onco again, we 
saw a Commodore-backed expo- 
sition draw enormouscrowdsand 
bring much deserved attention to 
the Amiga. For throe days, De- 
cember 6-S, 1991, thousands oi^ 
people 1 1 ocked to the International 
Center in Mississagiia to attend 
the nintli annual World of Com- 
modore, Toronto. .Attendees were 
treated to a host of exhibitors di.s- 
playing a multitude of Commo- 
dore products from VIC-20 
motherboards to CDTV. 

Many attendees came to the 
show just to see Commodore, 'the 
Amiga and its Commodore cous- 
ins were not the only spectacular 
products on d!spla\', hoivever. 

Digital Micronics demoed 
two of its dazzling products for 
the Amiga. They had se\eral 



Amigas showing off the power of 
DMl's Resolvor hoard. Tlie Re- 
solver boasted 1280x1024 resolu- 
tion ivhiie displaying a slide show 
of pictures so sharp, you'd swear 
you were looking at the live sub- 
jects. DMI also showed their new 
20MB l-loptical Disk Drive, a 
20MB, 3.5-inch floppy disk and 
special drive for the Amiga. The 
Floptical Disk Drive requires a 
standard SCSI interface and is 
compatible with all Amiga mod- 
els. The package includes all nec- 
essary cabling, powcrsupply,and 
a 20MB I-loptical Disk for a sug- 
gested retail price of S649. Addi- 
tional S.-'i-inch, 20MB Floptical 
Disks are available for about $20, 
which works out to $1 per MB, 
about wha t yon pay for a standard 
SOOK, 3,5-inch disk. DMI was 
showing a paint program which 
will be bundled with future Re- 



solver boards. The program, still 
in beta testing, will be a standard 
paint program with a few neat 
twists here and there, DMI pro- 
vided a list of software programs 
which are being prepared to run 
with the Resolver board, ADPw, 
Prcffiikttkm Mtislcr. DiimCADD, 
Calijiiiri, Dniw 4D Pro, Disk-Mus- 
ter, Image Mnsler, and Imagine are 
justa few of these programs. Other 
major software manufacturers are 
expected to make their products 
compatible with the Resolver, 

GVP added a new twist to 
fax modems with their latest 
power-packed creation, the 
PhonePak FaxMail System. Tliis 
innovative new peripheral turns 



and phone numbers. Other GVP 
products on display included the 
Digital Sound Studio, CiVP's low- 
cost entry into the world of sound 
and music. Designed for the semi- 
professional and hobbyist, DSS 
consists oi a sma 1 1 8-bit sound sa m- 
pler and editor which Is compat- 
ible with the 500, 2000, and 3000. 
Also on display were the Impact 
24 board and their new G-f"orce 
040 68040 accelerator for the 3000 
and 3000T, and GVP's host of ex-

(HAUG), from Burlington, 
Ontario, the Toronto Pet Users 




DMI's Floptical Drive. A floppy

Group, a Toronto-based Commo- 
dore computer club, and Track 3(5 
from Linden, Ontario. 

Retailers 

.■\lso appearing in outstand- 
ing nimibers were local computer 
retailors. AttendLng sellers display- 
ing their wares included Computer 
& You, Computer Evpross, Com- 
puter Odvssey, and Computer- 
Sense, Computer Variables, 
Comspec Systems, and Interzone 
Software, all from Ontario. 
Memory World, of Bensalem, PA, 
also came up. Other retailors also 
included lilectronics 2001, 
Thornhill Computers, The Soft- 
\vare Zone, and NTC Software, a 1 1 
of Canada. Computer Odyssey 
was gi\ing away free air fare to 
Hawaii with the purchase of a 
CDTV unit. All had complete se- 
lections of every software and 
hardware item one could possiblv 
imagine. Most had incredibledeais 



on CDTV units and A5U0 pack- 
ages that couldn't be beat. Quite a 
few CDTV units, along with the 
new keyboard, mouse, and disk 
drive peripherals, were sold. All 
in all, the retailers did well at this 
Commodore-backed event. 

Commodore 

Perhaps the most exciting at- 
traction of the World of Commo- 
dore was the Commodoredisplny. 
F\-erv Commodore producl avail- 
able ivas on display. Many com- 
panies joined in the display, dem- 
onstrating their products while at 
the same lime showing off the 
power of the Amiga. Gold Disk 
was one such company, showing 
off their exciting programs such as 
PrcfesfioHiil Page 2.0 and 
S/fincMrtfar. NewTek was another 
company there in spirit. Commo- 
dore featured a Laser Karoke, 
where you could sing or lip-sync 
to vour favorite song and be placed 
in the video for the song via the 
Video Toaster- That attraction 
drew m uch attention over the three 
day.s. Another feature of 
Commodore's booth \vas a draw- 
ing contest sponsored in part by 
Electronic Arts, Contestants cre- 
ated spectacular pictures using 
Delu.\e Paint IV. They were com- 
peting for a grand Prize of an 
.Amiga 500 with a 1084S color ste- 
reo mon i tor, Del tixe Video Softioarc, 
and the Uc/ii.vcAfi(srVCiiiisfn(i:f/(i)i

the three age groups (?-l vrs., 1 1 - 
16 yrs., and 16 and older) received 
either Deluxe Paint IV softivareor 
Mv Paint Software. Winners were

chosen by Charles I'achter, a Ca- 
nadian author and Amiga artist. 

CDTV was heavily demon- 
strated in Commodore's booth. 
New accessories such as the track 
Ball controller, special "CDTV 
Black" keyboard, mouse, and 3.5- 
inch flopp v d rive wei'e shown. At- 
tendees could try out v irtua lly any 
CDTV software title on any one of 
the available machines. Although 
there were more CDTV units avail- 
able tor attendees toexamine than 
any other Commodore product, 
the CDTV units were left to speak 
for themselves, as no special atten- 
tion was paid to them bv Commo- 
dore, judging by the number of 
CDTV units sold at the show, the 
units did a good jobof selling them- 
seh'es. 

A Disappointment 

It was soiuewhal of a let- 
down not to see NewTek at the 
show bu t theToaster made enough 
of a presence to place NeivTek 
there in spirit. A greater disap- 
pointment was the fact that Newer 
Technologies, the crea tors of what 
will be the hottest addition to the 
Amiga compatibles market, was 
not allowed to display their prod- 
uct. Newer Technologies is in the 
process of developing an .Amiga- 
compatible notebook computer. 
The notebook would have all the 
feature common to existing note- 
books; hovvever, it would feature 
the Amiga Operating System and 
full Amiga compatibility. Appar- 
ently, ne^ver Technologies and 
Commodore arc in the process of 
straightening t)ut some final de- 
tails associated u-ith the project 
and Commodore thought it best 
that Newer Technologies waited a 
while longer before officially an- 
nouncing the product.

Are You Gambling With Your Business ? 




'I don't need the 
SMG Extended 
Warranty because . 



'... systems today 
are so reliable they 
almost never fail.' 



Commodore builds some of the most reliable 
systems in the industry today. Yet all 
systems, from any manufacturer, can fait. And 
they do. Statistically, some fail every day. 
Normally when you cannot afford to be 
without your system. The larger, more 
complex the system, the greater the 
probability of failure. Someday, yours will 
fail, when you least expect it. 



"... nijust take it 
back to my dealer. ' 



Not all dealers are the same. Many do not 
provide any service. Of those that do, most 
are not Gold Service Dealers. Commodore 
has specifically approved Gold Service 
Dealers. They have the training and 
personnel to ensure that your failed system 
is repaired properly and quickly. You are 
either receiving Gold Service or you are 
settling for somelhing less. 



"... I have a 
Commodore Gold 
Service Dealer 
nearby. ' 



You're lucky. You can be assured of quality 
repairs by properly trained technicians. But 
even your Gold Service Dealer cannot provide 
coverage 7 days a week, 24 hours a day; 
shipment of the parts necessary to complete 
the repairs anywhere, overnight; access to 
on site nationwide coverage; and all at a fixed 
price for the length of your coverage period. 










Your Commodore Amiga Professional Series Computer System comes with 
one of the best warranties in the industry. Commodore Provides for a one 
year parts and labor, depot warranty. Your system is automatically eligible 
for free on-site CommodoreExpress Gold Service. All you must do is 
register your system with Commodore. But then what? Most small business' 
do not have the luxury of backup systems. If your system fails, you could be 
out of business until it is repaired. This can be very costly and time 
consuming. Now there is the SMG Gold Service Extended Warranty for 
Commodore Amiga Professional Systems. The SMG Gold Service Extended 
Warranty protects your system after the original Commodore coverage 
expires. Your system will receive the same Gold Service protection and 
support for up to two additional years! Can your business afford to be 
Y'ithout Gold Service Protection ? / 



The winning choice for your business is the 

SMG Gold Service Extended Warranty 
Commodore Amiga Professional Series Systems 



The Service Management Group is exclusively authorized by Commodore 
Business Machines, Inc. to provide the SMG Gold Service Extended 
Warranty Program for Commodore Amiga Professional Series (Amiga 2000, 
2500 and 3000) Systems. The SMG Gold Service Extended Warranty 
Program is available in the 50 United States. Original owners of 
Professional Series Systems, purchased through Authorized Commodore 
Dealers are eligible for SMG Gold Service Extended Warranty coverage. 
Even if your original Commodore warranty has expired, your system is 
eligible. Your system must be in good working order. Contact your local 
Authorized Commodore Dealer, CommodoreExpress at 1-800-448-9987 or

*\ \J ' w'it6 logictfased on the binary number system composed of only two 
'^ ( \digits: and 1, to represent the logical state of electronic devices as 
I '\ —'either "high" (1) or "low" (0). In binary, instead of ha\-ing numbers 
based upon powers of ten, thcv are based upon povs'crs of two. In our 
base ten decimal system, a number such as 103 can be expanded as: 
(l™)+(0"')+(3')=103. We never think about it, but the digits of decimal 
numbersare ordered so as to f i t into the uni ts, tens, hund reds, thousands, 
etc. positions. In binary, we position digits by powers of two, because 
instead of ten digits we haveonly two: count- 
ing in binar>- we have 1, 10, 11, 100, 101, 110, 
m, 1000, etc. The binary number 110 CnO'b 
in ARexx notation), is expanded to 
(l')+(l-)+(0')=decimal number 6. It is 
straightforward but inconvenient to convert 
number bases one to another, so ARexx in- 
cludes a complement of functions to do these 
conversions easily. Since binary number 
strings can become very long, programmers 
frequently use the hexadecimal systenx of 
numbering to make binary codes more com- 
pact and readable. In.slead of ten digits or 
two, hexadecimal is based upon 16 digits: 
through 9, plus the letters A through F. Con- 
\'ersion is easy bet^veen a base two binary 
number and a base sixteen hexadecimal or 
" hex " number beca use the hex base 1 6 is a Iso 
a power of hvo. Each four places of a binar_\' 

number represents one place in a hex number: For instance, the binary 
number 1111 translates to the hex number 'F'x in ARexx notation 
{decimal number 15), Another popular representation of computer 
number.s is octal or base eight numbers, where the digits run from to 
7. You will need to use many octal codes for things if you work with the 
PostScript page description language, becauscall PostScript Character 
Encoding Vectors are represented by octal numbers. It is also easy to 
convert octal numbers to or from binary as 8 is a power of hvo also. 
Three binary digits exactly correspond to one octal digit. All computer 
languages represent letters and printable characters, as well as control 



by Merrill Callaxvay 



characters by means of numeric codes expressed in one or more bases. 
ARexx provides built-in functions to con\-ert characters into or from 
their decimal, binary, or hex representations. 

In this exercise, we v:\\\ make a program to convert and display 
the translation of any number (in decimal, octal, hex or binary), or any 
short character string, into all the other representations. This is a handy 
utility when you are progranuning and need to convert between 
number bases or translate a character or string. ARexx has no built-in 
functions to handle octal numbers, but by constructing a coupio of 
simple interior fimctions we can take care of this. 

The ARexx conversion functions appear alphabetically in the 
sections on functions in both the Hawes 
and Commodore ARexx documentation. 
Some of the functions in Hawes \vereadded 
after the manual was printed, and are in 
the ARexx \1.15 update notes on disk. We 
w'M. list them here. The formal is always 
Ietter2k'tter(), as in x2c() which means to 
convert a hex number to a character. In the 
function set, d stands for decimal; c for 
character; b for binary; and x for hexadeci- 
mal. The ARexx conversion function set 
includes: d2c(), d2x(), x2c(), x2d(), b2c(), 
c2d(),c2x(), and c2b(). If yoit thinkabout it, 
you may decide that several possibilities 
are missing, such as b2d(), for instance. We 
will demonstrate how these missing func- 
tions ma\' be constructed easily by nesting 
the existing functions together. Also, since 
ARexx has no facilities for conversion to or 
from octal, we w'il! build that in, too, and make a b2o() and an o2b() 
function; o standing for octal. We will also demonstrate the correct use 
of the SELECT instruction for times when there are a number of options 
that we need the program to select from in its execution. We will first 
describe what we want to do by means of some pseudo code which is 
simplv a list of things we want the program to do, but in which we do 
not u'orry about proper syntax or exact instructicms. Since the program 
code itself is very readable, we can dispense with all but the most 
rudimentary pseudo code: 



ARexx includes 

a complennent 

of functions to 

do these 

conversions 

easily.

Pseudo Code for an ARexx Translator Program 

1. Get tlie usiT input siring .mti, if tlic usur input is .1 numbur olhtT 
than decimal, an option \o cicsigriatL' nnmber base: x ivitl denote hex; o 
octal; and b binory. The string and the option are to be separated by a 
space, or as an altemati\'e code, the string and option are to be entered 
on separate lines. Structure the input as an endless loop to allow 
multiple conversions. The user decides when to quit. 

2. Check the option and determine if the number base is \alid, i.e., 
for binary are all digits I's or O's; in octal, are alt digits less than 8? We 
will use ARexx's DATATYPE() function for all cases except octal where 
we will need to make a custom fimction similar to DATATYPEO to 
insure that all digits are less than S, since 'octal' is not an option of the 
ARexx DATAPiTEO function. 

3. Make a selection block to con\ert to the other representations 
based upon the user input: Decimal, Characters, Hex, Octal, or Binar\'. 
Code in the appropriate conversion functions, or make the missing 
ones with recursive calls to internal and, 'or custom functions. For 
instance, if the string to convert is binary, then we will need to use (or 
make): b2d(), b2x(), b2o(), and b2c(). Each selection block will ha\'c 
similar entries with appropriate conversions. 

Here is the program, called Hex.rexx (for its poetic sound). Note 
that ARexx instructions and functions are in UPPER case for clarit)-, but 
ARexx by no means requires this. You may use any case you wa nt. On 1 v 
host addresses and names of message ports in ARexx are case sensitive.

later. Yon will find DATA'l'Yl'liO documented in liawes, page %; and 
iii Commodore, pages 10-92. 7 he ne\l two IT clauses check for valid he\ 
and binarv numhers, respectively. Notice how they use the not opera- 
tor - attached to the function. This is the use of D.A.T.^TYP1;() to return 
a Boolean \nlue. 

An Internal Custom Function 

The final IF block before the SELECT instruction uses a custom 
internal function to accomplish the same thinj; as the D.^TAlTl'tiO 
testsabove, using a function procedure called octal!) to check for a valid 
octal number. We need a custom function here because 'octal' is not an 
option of the DATATYPEO built in function. The octal: PROCEDURE 
comes just after the main program, after the ENDof the DO FOREVER 
loop. This is an example of an internal ARexx function, hi the main 
program, you use syntax exactiv as vou do when calling an .ARexx 
built-in function: the name of the function with the argument in 
parentheses. Octal(ansu-er) calls the internal function and passes the 
argument ans^ver to it. ARexx knows it is an internal function, because 
of the label clause, octal: PROCEDURE, and the program control passes 
to that function when the main program calls it. The internal function 
first parses the argument sent to it (answer) into a variable called 
octnum, which is a protected \-ariahle, because it is not specifically 
expo.sed with the EXPOSEoption of the PROCRDU Rl". instruction. This 
means that anything we du to octnum will be pri\ ale tii Ihis fLinction 
and woLild in no wav influence the \aiue of an^■lhing in the main 
program even if there were a variable of the same name in the main 
program. If we n'ant to let the changes to any variable affect the values 
it has in the main program, then we must explicitly expose it by name 
in the procedure instruction. 

Now, still in the fimction, we do a loop: VX) WHILE octnum is not 
tlic null string. The loop parses the \'ariable one digit at a time and 
checks to see that it i.s not greater than 7. Digits greater than 7 arc illegal 
in octal (base eight) numbers. After it checks, it either finishes and 
RETURNS a 1 for true, or it sends back a tor lalse. 1 he main program's 
call to octal is in aix iFclause. so it is looking for a Boolean return, which 
we supplv. Internal functions communicate their answer to the main 
program by means of the RETURN keyword instruction followed bv 
an expression which ."XRexx evaluates if necessary before sending its 
value back to the caller as the value of the function. 



We now hove a handy tool for looking up the equivalents 

for various numbers and strings, 



line to opHon. The comma at the end of the first line is the continuation 
character which is used to continue an ARexx instruction line that is too 
long to fit on the page; in this case it is a longer SAY instruction telling 
the user to hit [Rtn] twice to exit. This substitution in the program will 
insure that any character string can be translated, e\en those contain- 
ing embedded blanks. After \ve parse with cither version, we reassign 
only the first letter of option in UPPER CASE to option, and next 
reassign option to the valueof 'X' if the user forgot and entered hex or 
h instead of Xas the option. This is just a small example of how you can 
make ARexx user friendiv, or eliminate common errors. 

The IF instructions test first to see if you ^^'ant to exit; then to see 
if vou ha\'e entered a decimal number, by checking the DATATYTE() 
of the string if the option is not specified or the option entry is the null 
string ". If answer is a NUMber, then the option is set to be 'D' for use 



Back in the main pixigram, the SELECT block is a structu re tha t wc 
Lise when there are several possibilities to select from. We have an ideal 
use of SKLECT here, because our string is one of five possibilities and 
cannot be two at once. Note the syntax of the SELECT block. It starts 
with the keyword on a line by itself and each possibility is accounted

was a valid decimal number, the option became 'D', so the only other 
time the option u'ill be null will be when we tr.inslate a character. The 
VVUl-N blocks ore lairly straightforward, hut notice the times we have 
nested functions of functions of function.s. This is an example of the 
compactness and power of ARexx. In the first WHE.NJ block, for 
instance, there is no ARexx function for convertingdecimal into binary, 
bLit we can nest two functions together as in the line: 

which first converts answer from decimal into character rcpresetx- 
tation d2c(), and then its result, a character string, is converted by the 
outerfunctionc2b()intobinarvnumberas we desire. Nested functions 
always work from the innermost parentheses outward. The ne\t clause 
is nested three deep. The outermost function isb2o(),another necessary 
custom function which converts from binary into octal numbers. 

Translating Binary to Octal 

Look at the last PROCEDURE in the program, b2p:, and let's 
discuss what happens. It recej\'es the argument from the caller and 
parses it into a wiriabie called binnum. Then the DO loop parses 
binnum into an array called num. which ends up with k-1 elements. 
Ho w d o you convert b i na ry to octal ? First of al I it takes a binary number 
three places long to describe only one digit of an octal number. Why? 
Because the eight octal digits run from to 7, so the largest single digit 
of octal, 7, is the binary number lU, which you'll recall is 
(I04)-i-(102)+(101)=7. For each place in an octal number, we therefore 
need three corresponding binary digits to represent it. Since the octal 
base 8 matches the pov\'ers of t\vo in binary everv three binarv- digits, 
then all we ha\e to do is count ever\' three binary digits from right to 
left and place that group's decimal representation into the placeholder 
of the octal number, it's OK to use the decimal representation, because 



at most, three binarv digits will equal 7, We simply need to count three 
binar\- digits from right to left, calculate the decimal representation of 
the three-place binary number, place that number as the least octal 
digit; and begin counting three more binary digits to the left of the first 
three; convert them; and place the result into the next place to the left 
in our octal string; and so on until we run out of binary digits. For 
example, we start with the binary string 010111)111. The first three 
digits starting on the right, III, con\erl via b2d() to decimal 7, so 7 is 
the least digit of the octal translation. The next three binary digits are 
110 and they equate to decimal 6, so our octal number is now at 67. Tlie 
final step convertsOlO into decimal 2. Tlie translation ofbinnry 01 01 10111 
is therefore octal 267. 

We accomplish this algorithm in ARexx bv means of two nested 
loops, one to count the binary digits backwards (since the binary digit 
array was built from left to right instead of from right to left); and the 
nested loop to evaluate e\erv throe binary digits. We don't really need 
to appiv b2d() to these digits as it's easier to calculate the result (ne\-er 
more than 7) directly. Otherwise we'd need to do something to get the 
binarv digits the other way around again, in order to apply the function 
b2d(). Notice that we actually decrement the outer loop counter! inside 
the inner loop, too. The inner loop contains an escape clause in the case 
that the arrav element iium.i is not a number. This is so because the 
length of the binary number may not be an exact multiple of three and 
at the leftmost group to e\ahiate in the binary string, the inner loop may 
trv to decrement past tile end of the binary siring. I'inally we build up 
the output variable finalsuin into an octal number string using concat- 
enation. We must increment i before we do another iteration of the 
outer loop because i was decremented once too often when we finished 
the inner loop. The function RETURNS finalsum to the caller. 

Translating Octal to Binary 

The other WHEN blocks operate in a similar manner. We find one 
more custom function to make in the o2b() function. How do wc turn 
an octal number into binary? To use the ready made ARexx functions 
as much as possible, we need to turn the octal number into a decimal 
called sum, and then use a nested pair of ARexx conversion functions 
to transform sum first into a character with d2c(), and then from a 
character into binary usingc2b(). By means of a simple loop in theo2b: 
PROCEDURE, we calculate the decimal number by computing the 
powers of 8 multiplied by the octal digits in each position, and then 
summing the results. 

We now have a handy tool for looking up the equi\-alents for 
various numbers and strings. Enter the program in a text editor and 
save as an ASCII file in \'our ARexx directory, Rexx:. Then, from a shell, 
enter rx Hex.rexx and start converting! You may notice that u'hen you 
enter certain numbers, as (hey are converted to characters, if they are 
not printable characters, they will actually do something, such as flash 
vour screen or perform a carriage return. Note also: In the ARexx 
manual, there is no mention of the limits of some of these functions, but 
the length of the string is limited and if voii enter too long a string, you 
will get some ARexx error messages. The intent of the conversion 
functions is to transform short strings and numbers. For instance, you 
may legallv enter 12 decimal digits but only four characters to convert. 
Longer strings will produce an error message. I wrote this program 
because I got tired of trying to remember which tables were in which 
book, and I hope it pro\es as convenient to vou as it has to me.

BUSINESS 





Forme, Iht' Amiga is. iboiit images. Images 
are a form oi^ langiiago tiiat carry an idea 
from ono piTson lo anollu'r. In duntistrv, my 
challLMigL' is first Uuinderslarid llKMniagL-stiiat 
peoplecarry wifii tlluni about IheirtuL'th. Thon 
I can help linem gul wliat lliev want from 
dentistry by dispiaving new images of tiie 
nvaiiable possibilities. The i\miga lias become 
a useful tool for (his purpose in niv practice. 

In using an\- tool, one needs to understand 
the job to be done. This prohablv gives vou the 
impression that 1 havea very firm grasp on the 
obvious. When I first started out to shop for a 
new computer, it v\'asn't that obvious lo me 
what I really wanted to do with it. Wo have 
used computers in our oflice for ten vears to 
manage the administrative functions, but 1 
wanted something to use for graphicalh- com- 
municating with my patients. There were many 
awiilabie choices. It came down to choosing 
among a Truevision product on either a PC or 
Mac, or the Amiga with the VideoToaster. I 
chose the Amiga /Toaster combination because 
1 could get more of ^vhat 1 wanted for the 
dollars 1 was willing to invest. 

My understanding of the use of this 
amazing toot is evolving. As I grasp its capa- 
bilities, I can sue more clearlv what 1 can do 
with it. I'd like to go over a few of the wavs in 
which I ha\'e found the .«\miga helpful. 

1 first started using video in niv office bv 
capturing images of existing conditions in the 
mouth. I use a small Panasonic CI'-KSltl2 
camera feeding into an SVIIS VCR and a con- 
sumer grade 20-inch monitor sitting next to 
my dental chair. I tell the patient to ignore the 
monitor while I'm taping. 1 then sit down with 
the patient and \vo review the \'ideo tape to- 
gether. Using a jog-shuttle control and the still 
frame capability of the VCR, I ha\e good con- 
trol o\or the images 1 want to review with the 
patient. When a person can see a single tooth 
nearh' filling the screen, I can do a much mcire 
effecti\'e job ot explaining problems or condi- 
tions needing attention. 1 can also pick up a 
view- of the x-rays and prt)ject them onto the 
monitor. This use of video images alone has 
been \ery helpful, but the fun begins when 1 
load some of these images into the computer. 




Images in 
Dentistry 

The Amiga assists a dentist 
in thie office. 

by Dr. Ken Larson 



I use a Sony V-3000 camcorder for views 
of a person's smile that I want to capture. The 
smaller Panasonic will do the job, but \ find 
that the larger camera works better for me. 
Clnce I ha\'e the images that I want to work 
with, 1 schedule the patient for a con.sultation. 
I can then do nry homework behind the scenes 
to prepare what I want the patient to see. These 
video images are digitized using the 
V id eoToaster or DCTV. The Sony V-5000 has a 
digital freeze-frame capability that simplifies 
this process. The DCTV unit will grab a frame 
in 10 seconds. The Toaster takes longer. Once 
the images are digitized, they are inter- 
changeableand can be used in either the Toaster 
or DC TV. 1 take a "before" view of the patient's 
smile that he or she wishes to change. I then use 
the DCTV paint package to simulate the 
changes in contour, color, brightness, or what- 
ever, I can replace missing teeth, eo\er old 
unsightly fillings, correct problems in align-

im.'nl,oto, 1 ivMSLic'liglilL'd iithowL'bisy thisiv,is 
to learn. 1 have not mastered nny af the paini 
packages on the Amiga, but I can do a lot with 
teeth in a \'ery sliort time. 

Once 1 have the "before" and "after" im- 
ages tlic way 1 want them for presentation, 1 
place the images in the To.ister tVamcstore lo 
prepare a little production for the consultation 
with the patient. Joe Blomberg of Alph.i Video 
in Minneapolis wrote an ARoxx program for 
me that does most of the ^vork. 1 go into the 
Character Generator portion of the To.ister to 
set up the patient's name for the production, i 
lea\e the Toaster londed and hit "CTRL.CTI^L, 
ALT, ALT" to get back to the workbench. Then 



Is the Amiga the 

latest cure for 

gingivitis? Not likely, 

but educational 

presentations like 

ttiis one created with 

Hyperbook, Scola, 

DCTV and an Anniga 

nnay be the first step 

to better oral 

hygiene and disease 

prevention. 



1 go into tiieARexx program through the Shell 
to instruct the program which frames to use for 
the "before" and "after" views and to set how 
man\' times I want them to cycle back and 
forth. 1 ha\-e the patient sit doivn in front of the 
monitor. There is a video camera on the wall, 
focused on the chair where the patient is si tting. 
I turn on a VCR that 1 have connected to the 
system, start the program, and \vatch the fun. 
The first thing the patient sees is his own live 
picture coming from the video camera on the 
wall. Then the patient's name rolls across the 
screen over his own image, followed by some 
titles and credits. The screen transitions to the 
frame of his smile "before" any changes. Then 




comes the "after" image that has been touched 
up. These two frames cycSe back and forth a 
number of times along with any comments or 
disclaimer 1 might wish to add to the produc- 
tion, l-inally, the patient'sown live image comes 
back up, wi th theclosing credits. I take the tape 
outof the VCR and give it to the patient to take 
home to show to friends and family. VVc then

I find this experience very satisfying. The 
quality of communication that results from the 
use of this medium is outstanding. The inter- 
personal rapport tends to be warm and com- 
fortable, and the likelihood of misunder- 
standing is miiiinial. For the person \v\w may 
have some fearful memories of deixtistry, this 
type of encounter has the potential to replace 
some of those negative images with something 
more positive based on truth and a present 
reality. 

Patient education is another area of my 
practice that benefits from using the Amiga. 
Most of what we call "education" at the adult 
level is simply an exchange of information that 
enables the adult to relate and assimilate the 
information to his or her own experience and 
situation to answer a question or need. 1 have 
used many different tools to assist me in this 
task through the years, but none have been as 
effecti^'e nor as pleasurable to useas the Amiga. 
Someone said that "the eye-way is the high- 
was' to the mind." I believe iL When I can use 
a visual medium to transfer a message, 1 find it 
much more effective than just talking. "Show, 
don't tell" is a rule that 1 have found \aluable. 

I use a combination of I lyiviivok, Scohi, 
and DCTV for most of our patient education 
efforts, although [ have done a few presenta- 
tions using .AmigaVision and Llan Performer. 
1 can bring full color DCTV images into both 
Scala and Hyperbook to put together with text 
and other graphics for excellent multimedia 
presentations tliatshow very well. When I first 
got my Amiga, I was disappointed with both 
HAM and the 16-color hires images that seemed 
to be the limit for use with Amiga graphics 
products. 1 could use Toaster images only in 
the Toaster. When DCTV was released, it was 
an answer to prayer. I discovered that 1 could 
combine the NTSC quality images from DCTV 
with output from Sea la and display both on the 
composite monitor. I found that it works if I 
avoid overscan and am careful with text place- 
menL If the coded information along the top 
and left border of the tXTTV image is cropped 
or disturbed, you get no image or distortions in

the image. Once these limits aro LindersttKici 
and nllDwed tor, I have been \'ery satisfied 
vvith the results I'v'c been getting. 

The presentations I have been gi\'ing ha\'e 
fallen into twocategories: Formal (planned and 
prepared) and informal (impromptu and ex- 
temporaneous). 

Hvpcrbook is very helpful when I'm do- 
ing a presentation where 1 might want to move 
around randomly within the presentation, I 
have a library of stock dental images that 1 use 
to illustrate \'orious conditions and services 
that a person may need to know 
about. I use these images in a 
number of ways. One 
Hyperbook program is simply 
acataloglistingofallthodental 
pictures I use. 1 can sit down 
with a person and click on 
any of the listed pictures to 
display that picture. 1 use an- 
other Hyperbook program to 
teach the basics of what a 
person needs to understand 
about gum disease to treat 
it successfully and save 
teeth. Tliis is a little more 
forma! in the sense that 
there is a planned script 
involved with a logical 
flow of information. A 
strong point of 
Hyperbook is that 1 can 
follow the script with 
much improvisational 
flexibility. I can move 
around within the pre- 
sentation by just click- 
ing on buttons to re- 
peat a point, empha- 
si7.c a point or to skip 
an irrelevant point. I 
use drawings of den- 
tal structures along 
with text on the RGB 
monitor, and 1 can 
show related photo 
quality DCTV im- 
ages on the composite monitor by clicking 
buttons on the Hyperbook page. I can't use a 
DCTV image as a page in Hyperbook, nor can 
I put any buttons on these images, but the 
presentations are still acceptable, 

Scala isanotherpresentation package that 
I use often. Its ease of use makes it nearly 
transparent in working out a presentation. You 
can use the tooland focuson the job. 1 useScala 



I use a 

combination of 

Hyperbook, Scola, 

and DCTV for 

most of our 

patient education 

efforts, 

to put together text and graphics to illustrate 
and tench. 1 have found that I can design pages 
in Scala and import tliem to Hyperbook for a 
quick, easy and very attracti\-c layout design. 
I use many of the stock backgroiuids packaged 
wi th Scala, bu t i t is \'cry cas>' to import my own 
backgrounds that are specific to my particular 
use. One of the many uses of Scala is being able 
to bring up text line bv line, having the preced- 
ing line fade to another color to emphasize the 




current point being made. With care, text can 
be overlaid on DCTV images to do the same 
thing. If I keep the text to the center of the 
screen, wa tch my colors, and avoid the 3-D text 
effect, the resuits are quite good. 

Speed is one of Scala's major strengths. 1 
can put togethera presentation in minutes that 
looks groat! Scala pre.senlations can also be 
designed to run as a standalone show and with 
interacti\'e buttons, although I ha\'e not used 
these applications yet. 

Informal "electronic chalk talks" are an- 
other effective and exci ting use of the Amiga in 
my office. When a patient asks about a proce- 
dure or problem, 1 can sit down with him or her 
and illustrate my explanation with one of the 
paint programs. For example, in discussing the 
dreaded root cana!, I can load a stock drawing 
of some teeth into DCTV paint and show u'hcre 
the root canal is, %vhy there is a problem, what 
we can do, along with the risks and benefits. If 
1 wanted the person to have a copy of this 
illustration, 1 could simply dump it to video- 



tape. ! can illustrate the preparation of a tooth 
for a crown, draw on the patient's own X-ray 
pictures or any number of different things to 
clarify ^vhat is often very clear to me but \'ery 
obscure to the patient. 

We now ha\'o two separate computer 
svstems in our office — one for the administra- 
tive functions and patient records, and the 
Amiga, which I have designated as our "com- 
munications computer." I am looking forward 
to getting full 24-bif RGB capability for work 
with graphics from Scala with true 
photorealistic i mages on the RGB 
monitor. DCTV has been a major 
improvement, but composite 
images still jitter and bleed, and 
don't come near to the quality 
of a 24-bit RGB image. The 
Toaster is helpful, but it too is 
limited to composite output. 
I'm \s' a i t i n g to see lun\' 
Colorburslcompares with the 
Firecracker before 1 take that 
next step. 

Another limitation I 
have found with the Toaster 
is that 1 need to buy a whole 
lotmore equipment before 
1 can make full use of its 
video production capa- 
bility. 1 had envisioned 
sophisticated produc- 
tions with just the Amiga 
and the Toaster, but I 
soon discovered the 
need for frame-accurate 
VCRs, editing control- 
lers, etc. 

Tlie Amiga and 
the use of video have 
become a substantial 
asset in our pracHce. 
1 would not want to 
practice dentistry 
without this com- 
iiuinieation capa- 
bility. 11 has made 
my work more 

pleasant, it has enhanced our rapport with our 
patients, and it has paid for itself in increased 
productivity. It is a choice that 1 will benefit 
from for years to come. "AC*

Amiga on Call 

The Amiga at work in the doctor's office. 

In/ Dale B. Call, M.D. 




xTL 



s computers become more and more a 
part of our e\'orvda\'livcs,thLM'L' are many 
who feel intimidated. The fear of the "un- 
known," the fear that they will look foolish or 
not be able to learn to use the coniputur, the 
fear that they will "break" something, all make 
it difficult for some to incorporate the com- 
puter into their lives and use it on the job. Of 
those groups reluctant to use computers, one 
of the last "hold outs" is the medical profes- 
sion. Yet, as more ho.spitals become computer- 
ized, and more phy.siciaas learn how much 
time computer.H can save, especially with ac- 
counts, an increasing number of medical of- 
fices are installing and using computers. Usu- 
ally they are used to maintain demographic 
information on patients or to keeo accounts. 
There are a few adventurous souls v^'ho have 
made the computer an integral part of almost 
everything they do. This is the story of one 
such doctor. 

I was first introduced to the computer in 
1984 when I got a Commodore 64 for Christ- 
mas. At the time, I was working for an IIMO 



The Amiga's 
power, versatility, 
and good bedside 
manner mal<e it 
the perfect 
addition to this 
doctor's office, 



(Health Maintenance Organization) as a sala- 
ried physician. 1 found myself spending at 
leasi an hour a day working or playing on the 
computer, and sometime continuing into the 
wee hours of the morning. Besides games, 
there were database programs to keep track of 
patients and word processing to prepare cases 
I would do for my medical boards. Tlierc were 
art and graphics, music, and telecommunica- 
tions. It would seem that 1 u'ould just begin to 
get satiated with one area, when I would be- 
come enthralled with another. Aboutthis time 
the announcement was made regarding the 
upcoming release of the Amiga. Since the 
Amiga was to have been fBM-compatible and 



we were using IBM in the HMO I was working 
at, 1 thought the Amiga would be an ideal 
computer for me. l was sure there would be a 
Commodore-64 emulator, and this would al- 
low me to use the same computer for both 
work and entertainment. Asa result, 1 became 
the owner of one of the first Amigas produced. 
Although things did not work out as I had 
foreseen, it was still one of the best purchases 
I had ever made. 

Tlie IBM compatibilitv and the Commo- 
dore-64 emulator took longer to come to frui- 
tion than 1 had anticipated. In the meantime, I 
became impressed with the four voices with 
stereo sound, the art programs with 32 to 4096 
colors, the ctigitalized images that could then 
be used in the paint programs or in animations, 
and the ease of using the mouse or the ke}'- 
board for inputting data. Suddenly the Com- 
modore 64 paled, compared to all I could do on 
the Atniga. 

During this time, 1 left the HMO and set 
up practice on my own as an Obstetrician and 
Gynecologist. 1 purchased the "Transformer" 
and Lotuf 1-2-3 for the IBM and was looking for 
ways to use the computer in my newly estab- 
lished practice. 1 wanted m\' office to be "com- 
puterized." Unfortunately, all of the programs 
for physician office management run under 
the IBM format and were impractical \vith the 
"Transformer." Plans for the "Sidecar" were 
announced and although the shipping of these 
was limited, 1 made sure I got one. For those 
not familiar with the Sidecar, let me explain

me to do more sophisticated

lustrated instructional 
materials, and con- 
tinue to e^;periment 
and learn. For the 
next two years, 
this was the 
heart and 
sou! of my 
office. 




softi\-are a Hows networking, and there are three 
stations set up in the office. Due to all of t!ie 
advantage.-i with regard to graphics and video 
capabilities of the Amiga, 1 have upgraded to 
an Amiga 2500 with a 40MB hard drive and 
5.\IB of RAM. I also have a 
Winchester drive with 
Syquest which gives me a 
44iMB removable cartridge. In 
addition 1 have installed a 2S6 
AT IBM bridgecard with an- 
other IBM-dedicated 4t)MB 
hard drive in the Amiga. This 
has allowed me to transfer my 
old svstem and files to the 
Amiga. Since there is no port 
to easily transfer the patients 
on the old medical software 
s\'stem to the neu^ system, they 
had to be done manuallv and 
therefore ive transferred only 
the open accounts. By having 
the old system readily avail- 
able, we are able to easily look 
up old accounts on the same 
compLiter. I am using ATalk 
111 to emulate a VT 11)0 termi- 



nal to network with the Unix system. Essen- 
tially, I can have three computers running on 
the Amiga at the same time, and flip back and 
forth between them as I need to. 

Besides the day-to-day office routine — 
billing, insurance forms, encounter forms, cor- 
respondence, pa lient demographics, accotints, 
and appointments — 1 have used the Amiga to 
produce two videos. One is on the menstrual 
cycle which 1 use for various talks and pre.sen- 
tations. The other is on the beginning of life. I 
ha\-edigitalii;ed \arious pictures of the differ- 
ent stages of development and put them to 
music. I plan on adding a narration, either 
audio or written. Using the Amiga, 1 have 
digitalized a picture which I the adapted to a 
logo which is being use for mv ad in the phone 
directors', t have seen a patient education or 
self-learning program used forOB/C\'non the 
Macintosh, but with ail of the extras the /\miga 
offers with better afi'ordahilitv, 1 would like to 
de\'elop something similar for the Amiga.

each morning for the patient's chart, and main- 
tain a current "electronic historv" in the com- 
puter that would be accessible not only from 
the terminals, but also from outside the office 
using special passwords. 1 am excited about 
the agreement between Unix and Amiga. This 
should allow more ot the bitsiness sottware to 
become a\'ailable for the .Amiga user, while 
still allowing us to take advantage of the unique 
applications of the Amiga in graphics, music, 
and desktop video. 

As the uses and applications for comput- 
ers,and especially the Amiga, continue to grow, 
there will be more and more opportunities for 
allot us to be enriched b\' this fabulous media.

Anyone iin*oi\L'd wilh desktop piililisliing 
knows lh<U Ihu AmiH'i Ciin hold ils oivn 
agninsi lliL-compctilion. In video, it's in ii class 
by itself. Well, it's ii tough competitor in the 
field of sign making too. 

Ttie Amiga is perfect for scanning a logo, 
tracing it to a structured draiviiij;, integrating 
type and otitpiitting to a viiiyl-ciillinj; plotter. 
The process is relatis'ely simple and does not 
require expensive specialized software. The 
price of vinyl cutting plotters starts at less than 
$4000. 

Most of the lettering on signs todav is 
vinyl, not paint. This vinyl is a thin film of 
plastic that has a very sticky adhesive on one 
side. It comes in rolls or sheets \vith a protec- 
tive paper backing on (he adliesi\'e side. ,'\n 
image can he cut into tiie vinvl — to, but not 
through, thebacking sheet — and the unwanted 
vinvl weeded out. The remaining image is then 
transferred to the 
sign. 

Many sign 
shops have comput- 
ers hooked up to plot- 
ters which machine- 
cut the vinvi. Basi- 
cally, plotters trans- 
late the X and Y co- 
ordinates of an im- 
age into the path that 
the knife blade fol- 
lows to make the cut. 
The blade travels left 
and right on the X- 
axis and the vin\'l 
travels backward 
and forward along 
the Y-axis, alUnx'ing 
the image to be cut in 
any direction. Plot- 
ters usually ha ve pen 
attachments as well 
as blades, so you can 
test your plots before 
using them on the 
expensive \inyl. 
1 started out making signs by designing 
them on the Amiga and outputting iheni to 
transparencies on my PostScript printer. Then 
I projected them to the size that 1 needed and 
cither hand-lettered directly on the sign or 
hand-cut the vinvl and applied it. It didn't take 
too many repeat jobs to realize that there had to 
beabetter way. Why couldn't I cut \-inyl on my 
Amiga? 



Sign Making 

Using Your Amiga to Create Professional Signs. 



bi/ Karen Pringlc 



I spent countless hours in(.]uiring into 
plotting and vinyl cutters, but the plotting 
peopledidn't know nnvthing about the .Amiga 
and the .'\miga people didn't know anything 
about plotters. 1-inally Commodore themseh'es 
put me in touch with Jeff Ginn. Jeff had been 
making signs and sets for the n\o\'ics with his 
Amiga 501) for .several years. After lots of direc- 
tion from Jeff, I was on my wav. Thanks, Jeff. 

An Amiga 500 can be used, but I have a 
2.5Mhz Amiga 3000 with (iMB memory, 2MB 
Chip RAM. and a IDIIMB hard dri\e. 1 also lise 
a Migraph hand scanner, an NEC LCS')0 Post- 
Script and Laser printer, and a Roland CAMM- 
1 Plotter that pen plots and cuts vinyl. Pro 
Vi'cf nr or Pnifi'ssiorm/ Dnrn ' and T(i»c/i- LI/ 1 for the 
.scanner a re ( lie on 1 y .-iolt wa re necessa ry . Other 
drawing packages may be able to do the job 
too, but these are the only tvvo that 1 have used. 
I u.se Workbench 2.0 exclusively now tha t most 
of the software is cimipatible. 

l-or this overview of the sign-making 
procedures, 1 won't go into a lot of detail as to 
how to use the softivare or hardu'are, as the 
manuals cover that quite well. There are prob- 
ably other wavs to achieve good results, but by 
trial and erroi', the.se metliods work best for 
me. If anyone lias any suggestions or ques- 
tions, I would be glad to hear from them. 

Someof the procedures mavseema little 
complicated in the explaining, but are actually 
fairly simple once they're understood. 
ProVector and Pro Draw are dra\ving pro- 
grams, not sign packages, but both can do the 
job of producing signs extremely weli. 

Scanning 

If you have a copy of the logo or drawing 
that you want to incorporate into your sign, it 
is a simple matter to scan the copy to a bitmap. 
1 use a black and white hand scanner at 400 
dots per inch, set on letter or line. If you're 
short on memory or disk space, 100 or 200dpi 
will work too. Plotters can cut onlv from struc- 
tured images, so the bitmap must be converted 



by tracing, either by hand or withan auto-trace 
program. Generally, scanned type is easier to 
trace manually because auto trace does not 
make square corners. It does a nice job on 
illustrations, although you may find there are 
more control points than ncccssar)'. Scanning 
often produces an image too large for Pro 
Draw to trace, as this program has a maximum 
input size of 1008 X 1 008 pi.xeis. I use Touch-Up 
to bring tt doivn to a more useable size.

theimage as possible. I 
usually put an appen- 
dix of .tu on tho 
filename to keep the 
files obvious. To 
change the size, use 
TU's \'iewer to make 
note of the actual size — 
example, 1428X x 
1232Y. As the final size 
must be less than 1008 
for both X and Y, di- 
vide 1000 (instead of 
1008— it's easier) by 
the largest dimen- 
sion — in the e.vample, 
1428 — which is about 

70%, and then take that percent of the other 
dimension— 70% x 1232 = 863. This makes the 
new dimensions lOllOX x 863Y. Back in the 
TU's page/clip requester, change the size of 




many control points and is awkward to edit. 
Click trace and the clip is soon on disk. I had 
one bitmap that had a large, very ornate, con-

the page and tho clip to these new dimensions. 
This keep.s everything proportionate. Select 
"wipe" rather than "adjust" when the requester 
appears. Load the clip back in Touch-Up and 
save it again. The image can be smoothed up if 
necessary to make a cleaner trace. The Trace 
program for I'roV'ector is not released as of this 
writing, but 1 understand that there will not be 
a size limitation for the bitmaps. 

Auto Tracing in Pro Drew 

Now that the bitmap is the proper size, 
call up Pro Draw's Trace program. Designate 
the picture file to be traced, the output file, and 
the clip name. 1 usually trace line drawings at 
five pixels fit. 1 often set it to fill the lines incase 
I want to use it in anotherapplication and don't 
want the inline, outline effect. This doesn't 
affect plotting, because HPCL onlv uses the 
outline co-ordinates. Fill or no-fill can also be 
changed in ProDraw itself later. J will trace 
very intricate images at two pixel fit. I have 
found that using too low a number creates too 



IWOn control points on that single line. The 
trace program seemed to go into a continuous 
loop. 1 put the image back into Touch-Up, 
broke the line into smaller segments, and it 
traced fine. Next, open up Professional Draw 
and create a 22" x 22" page. This ensures that 
the clip \vill fit on the page when it is imported. 
Once tho clip is on the page, it can be moved to 
the upper left corner and the page size altered 
to fit. There's not much to cleaning up. Remo%'e 
any untidiness and eliminate the small unnec- 
essary areas. As with so many things, the sim- 
pler, the better. If there are right angles in- 
volved, you'll find that the trace program 
rounds them off and they w'M have to be 
squared up. You may a Iso f i nd that mnnv of the 
control points can be eliminated. 

Manual Tracing in ProVector & Pro 
Draw 

For Pro Vector, import your bitmap into a 
page. The page size can bo adjusted after im- 
porting if it is too small. The bitmap will be 



black, bu t i f vou change 
your border (line) color 
to red or blue, you will 
be able to see your 
structured image as 
vou develop it. Tho 
manual tells vou how 
to draw with the soft- 
wa re, but here are a few 
tips to make it easier. 
With version 
2.0, to make smooth 
curves, place your first 
control point of \'our 
next curve in a con- 
tinuous line from the 
anchor point and the 
last control pointof the 
previous curve. This 
ta kes a lot of the guess- 
work out of wltich di- 
rection to go and keeps vour cur\'es smooth 
without a lot of editing. In other words, tho line 
will be straight from the second control point 
of curve one to the first control point of curve 
two, passing through the joining anchor point. 
Also ivith type and other consistent objects, 
this line can be horizontal or vertical, so that 
even more of the guesswork is removed. i\'ou' 
you just have to U'orry about how far away to 
place the point. If you place i t about 11/2 times 
as far as you want the curve to go, vou will be 
close, and have very little editing to do. Don't 
forget to change from the curve tool to the 
straight line tool when necessary. If you are not 
creating closed objects, make sure you get 
intersecting lines to meet. This facilitates weed- 
ing the unwanted \'inyl later. 

Version 2.1 has 
iieen released and it 
has a bezicr tool that's 
even easier to use. 
Straight a nd ciirve are 
one tool, and curves 
are put in by placing 
the two anchor points 
first, drag and release 
to place the first con- 
trol point, and click to 
place the second con- 
trol point. You can see 
the curve you are cre- 
ating while yon are 
doing this — making 
things easier. The 
same principle ap- 
plies, keeping the line 
between two control 
points straight 

through the anchor 
point. To create 
si raighl lines, just keep

clickingalthu junction points. Ifyou'rehaving 
trouble getting; tlie curve you wnnt, you can 
mal;e adjuslmunts wtien you are editing. 

The principles of smooth curves in 
ProVector also apply to Pro Draw, although 
the method of getting them is quite different. 
Drawing your first curve, place the control 
point (A) and drag the tangent in the direction 
that you want the cur\'e to go (B), release the 
left mouse button at the distance, again about 
11/2 times the arc distance, and place your 
control point (C) where vou want it. To con- 
tinue to the next cur\'e, keep the left button 
pressed and drag back in the direction of the 
previous curve (D), release and piace your 
next point (E) as you continue your cu r ve. This 
is the normal n^ethod for Pro Draw to create 
curves with a straight tangent on each side of 
the control point. If you find this to be awk- 
ward, there is an easier method, but it creates 
only one tangent per control point and conse- 
quently is not quite as flexible for editing. In 
effect it draws single curves and joins them. To 
do this, draw the first curve as described above 
(A and B) and place the second control point 
(C). Now instead of continuing with the next 
curve, press ESC but leave the pointer on that 
control point and hold down CTRL to join the 
last cur\'e to the new one, and drag (D) as if 
making a first cur\'e again. This keeps your 
first curve from changing as it does in the first 
method. Some find this easier to work with. As 
with ProVector, you can fix inaccuracies by 
editing. 

Page Size and Final Layout 

When the drawing is finished, add out- 
line type or any other elements needed. Make 
sure you click on kerning when setting the 
type in Pro Draw. Ail the components can now 
be sized and moved to their final positions, 
keeping the layout to the top left corner. Make 
the page as small as possible while still con- 
taining all the copy. This can save a bit of vinyl. 

Each brand of plotter has its own maxi- 
mum page si/e and maximum image size. The 
Roland CAMM-1 that I use has a maximum 
sheet size of 20" x 60" but the maximum image 
size is about 18,8" for a 20" roll or sheet of vinyl 
and 13.8" for a 15" roll. The page size must be 
kept within these dimensions. Rolls and sheets 
of \'inyl come in quite a variety of widths, but 
15" and 30" are the most common. 
ProVector.FFP (fast floating Point) has an al- 
most infinite page size limit, so you can make 
your page size the finished size of your sign. If 
the final size is larger than your plotter's limi- 
tation, it can be output in several pieces using 
the partial plot facility and assembled in posi- 
tion on the sign. Pro Draw has a maximum 
page size of 22" x 22". If the final size that 1 need 
is within the range of Pro Draw and my vinyl, 



for instance 13.5" x 20", I make my page size the 
actual finished size. To plot within 20" x 32", 1 
make my page size in Pro Draw 9" x 15" and 
scale it up 200% just before plotting. I then 
arrange the elements within this area. The 
image can be less than 1/8" from the edge of 
the page. 

To summarize, let me stress that the page 
size in Pro Draw can be any size as long as 
scaling it up does not exceed the maximum 
image width or length that the plotter allows. 
Actually, a 1" x 1" page size could be scaled 
1350'';i and still be plotted on 15" vinyl. 

Plotting and Scaling 

I use the HPGL.big plotter driver with 
ProVector. It is necessary to change the tool 
type width and height of the driver if it is not 
the same as the page size. This is done from the 
\vorkbench by selecting the HPGL.big icon in 
the ProVector PVdriver drawer a nd cal I ing up 
information which opens up the window where 
you can make the changes. The tool type 
ROT90=true will plot from the side of the page, 
so that a 40" x 13" (landscape) will plot prop- 
erly along the roll of vinyl. As long as your 
plotter is set up properly, now all you have to 
do is select full plot from the project menu, and 
choose the HPGL.big driver and you're cut- 
ting vinyl. 

Changing the Pro Draw plotfile is more 
difficult to explain than it is to do. Pro Draw 
does not plot properly outputti ng stra ight from 
the program. 1 understand that the current 
HPCL driver is set up for drafting plotters, but 
Gold Disk is now making adjustments to out- 
put to \inyi cutters. There is a line of prologue 
that has to be added to the plotter driver, at 
least for the CAMM-1, 

Now that the project is ready to cut, out- 
put HPCL todisk. 1 have a directory set up that 
1 put mv plots in. It's on the data: partition of 
my hard drive, so my plots go to datarplot/ 
name. Next go to the Shell and enter "memacs

dala:plot /name". This sends the file to memacs 
for editing. When the file is on the screen, the 
first line reads "SC 0,1234, 0,5678;". The is the 
number zero. The other numbers are the Pro 
Drav\' co-ordinates for the page size, not neces- 
sarily 1234 and 567S. The new lino is needed 
abo\'e this line, so with the cursor on the S, 
press return and cursor up to this new blank 
1 i ne. En ter "IP0,0,2468,1 1 356;" (no spaces) . Note 
that the co-ordinates are 2 times the Pro Draw 
co-ordinates. No matter what scalingyou need, 
these co-ordinates will always be twice the 
original Pro Drav%' co-ordinates. Also notice 
that the page size co-ordinates in the "IP" line 
are in the third and fourth position instead of 
the second and fourth position as in the "SC" 
line. For some reason, the CAMM-1 changes 
the position of the co-ordinates for initializing 
(IP) and scaling (SC). You also have to close up 
the space between the 1234, and the in the SC 
line. The plot file now reads; 
IP0,0,2468, 11356; 
SC0,1 234,0,5678; 

This will plot same size. Save the edited file 
under the same name and exit memacs. 

Scaling with Pro Draw is sometimes nec- 
essary if the page size is smaller than the final 
required size. This is also edited in memacs 
and is done to the SC line. To plot same size, 
keep the original Pro Draw co-ordinates. To 
plot 200"ir, divide the original co-ordinates by 
2. To plot 400'^, divide by 4. To plot 50%, 
multiply by 2. The Pro Draw co-ordinates 
change inversely to the size change. For ob- 
scure size changes, invert the fraction and 
multiply. 

Example: 165% is achially 165/100. Invert this 
-100/165 

100/165 X 1234 = 748 100/165 x 5678

The revised plot file should read: 

IPaO,2468,11356; 

SC0,748,0,3441; 

Save the file and exit memncs. 

Now \ve can ttim on the plotter and make 
sure it's set to the mode that's needed. Instruc- 
tions for this will be in your plotter manual. In 
the Shell, enter "copv data:plot/name to par:". 
Now you're plotting. Just check to make sure 
that the blade is cutting to the backing sheet 
but not through it. The whole procedure is 
much easier to do than it sounds. Here's a 
condensed version of it for Pro Draw; 

'Most of the steps are not necessary if scanning 

and scaling are not required. 

1.* Scan and save bitmap. 

2.* Resize bitmap to fit Trace in Pro Draw. 

3.* Trace bitmap manually or auto trace. 

4.* Import auto traced clip into Pro Draw, 

5.* Clean up dip. 

6," Add type and other elements. 

7. Arrange copv and page to fit final re- 
tiuirements. 

8. Output HPGL to disk. 

9. Shell - plotfile to memacs 

10. Insert IP line, using Pro Draw co-ordi- 
nates doubled. 

11. Close up space between SC 2nd and 3rd 
co-ordinates. 

12,* Scale SC co-ordinates. 
13. Shell - copy to par: 

As you can see, it can be as simple as six steps. 
Here's the condensed version for ProVector: 

1.* Scan and save bitmap. 

2.' Trace bitmap. 

3.* Clean up trace, 

4.* Add type and other elements. 

5. Arrange copy and page to fit final re- 
quirements. 

6. Make sure plotter driver tool types is set 
to page size 

7. Output to HPGL.big driver. 

Now that the \'inyl is cut, the non-image 
\inyl is carehiUy weeded out. I usually use a 
scalpel to score between the lines of copy or 
illustrationsand workonsmallersections. Next 
a sheet of pre-mask is laid on top of the vinyl 
that's left on the backing. The pre-mask is like 
a large sheet of masking tape that is less sticky 
than the vinyl and holds the image in place 
when the backing is pulled off later. Position 
the pre-masked \'inyl on the sign (with the 
backing still attached) and tape it all along the 
top edge securely. Lift the bottom edge and 
slowly remove the backing sheet, starring at 
the hinged top and burnishing the vinyl down 
asyou gradually pull tliebackingawav.l'irmlv 



ProVector and 
Pro Draw can do 

the job of 
producing signs 

very well. 



reburnish with the pre-nmsk still on. The 
pre-mask can nou' be remo\'ed by lifting a 
corner and pulling it back along its own 
surface so that it doesn't try to lift the vinyl. 
Burnish again, paving particular attcnrion 
to the edges. You mav find that there are 
little air bubbles. These can be punctured 
with a pin (not a knife) and the air pushed 
toward the pinhole. Some signmakers use a 
weak soap and water solution or windex to 
apply the \inyl. This allows it to be moved 
for positioning for a very brief timeand then 
burnished down. I've tried both, but for 
most applications, I prefer the dry transfer 
method as described above. 

It's best not to try to cut too fine a line 
or too intricate an illustration. Bold and 
simple usuallv provide the best plots. Sharp 
plotter blades can also help when cutting 
finer plots. There are ways to plot projects 
larger than the plotter can accommodate. In 
Pro Draw you can hang 'grouped' copy off 
the edge of the page, plot the page to disk, 
move the copy to get the extra part back on 
the page and plot it again. This will give vou 
two or more plots that can be pieced to- 
gether later. In ProVector large signs can be 
cut in smaller segments by magnifving a 
section to the screen size and doing a partial 
plot. The latest HPGL.big driver has a tiling 
feature which allows any size sign to be cut 
into smaller pieces automatically. 

If you are planning to use a drawing in 
a postscript file, vou should he aware that 
PostScript will refuse to print a job that 
contains an object with more than 1500con- 
trol points. It pretends that it is processing, 
but doesn't print. The wav around this is to 
break the object into smaller objects or make 
compound objects (Pro Draw) or sub-poly- 
gons (ProVector) on !y of the ixecessary parts, 
such as A's but not L's. 

Colors can be plotted separately bv 
copying them to new pages. Shadow type 
etc. can be made be cutting the same image 



twicein different coloursand assembling them 
on (he sign, ofl'sel lo the side and down. 

Troubleshooting 

in Pro Draw, most of the problcnis that 
occu r a re the resu It of incorrect co-ordina tes in 
the plotfile. Double check that zeros are not 
O's, and that commas and semi-colons are 
used and that there are no spaces. In ProVector, 
make sure that the plotter-driver page size 
coincides with the actual page size. Cabling 
that is too long can create a problem as well. I 
usually plug the plotterdircctly into the paral- 
lel port and use the switchbox only for the 
scanner and printer. It's a good idea to test the 
plot on paper with the pens if you are not too 
sure of the result. You can save vinyl and also 
gi\'e your customer a full size proof. If some- 
thing is wrong when vou 're cutting vinyl, 
from the CLI stop the plotter immediatelv and 
replace the \'inyl with paper and pens. If vou 
are plotting within ProVector, the cancel but- 
ton btitlon works almost immediately. The 
buffer takes a long time to clear and will 
resume cutting after you turn it on again. This 
is the \'oice of experience talking — vinvl is 
expensive. 

There are many more adjustments that 
can be made, and shortcuts that can be taken, 
but 1 have tried to give a verv basic look at 
what can be done without going into too m uch 
detail. Tliere should be enough information 
here to get you plotting with software that you 
already have, and wilhoul too much confu- 
sion. 

The wonderiul part about using the 
Amiga in mv business is that 1 can supph- mv 
customers with promotional material, statio- 
nery, signs, and truck lettering. I don't need a 
lot of expensive specialized equipment or 
software and the image I create is consistent 
throughout because there is no chance that an 
outside supplier is going to misinterpret mv 
layout. The real bonus is that 1 io\'e working 
with m)' Amiga, and that makes work fun.

re: 2.0 patch 
source: reader mail 

Joseph Fentort, an Amiga owner 
from Barker, TX with an Electrical 
Engineering degree wrote a long 
letterregardingthe Applied Engi- 
neering High Density disk drive. 
Hopefully his information will be 
enough to soh'e the prohlem for 
AEHD drive owners. The infor- 
mation he provides was not veri- 
fied by Applied Engineering, but 
he made it awiilable in the hope 
that some software developer 
mightbe able to create a patch that 
works on Ihe drive under Work- 
bench 2.0, 

He writes: 1-irst, the .A.EHD 
usesaspecialdrivelD. Ifyouonly 
read the first two ID bits (as most 
programs do), you vvill not notice 
anything different; If you read all 
32blts(asA-Maxdocs), the AEHD 
will appear to be a non-standard 
dri\-e (ivhich is «'hv A-Max does 
not use AEHD drives during 
emulation. (He has a custom 
loader that patches this and a 
coupleof other things.) Ifyou AND 
the 32 bit ID with SFFl FFFFF, you 
will ahvaysget an IDof S0F03FFF1-. 
The three bits ANDed out tell you 
about thestateof lhedri\'eand the 
tvpe of disk inserted; specifically, 
bit 23 is if a disk Is in the drive 
and 1 if there isn't a disk inserted; 
if there Is a disk In the drive (AND 
ONLY IF THERE IS A DISK IN 
THE DRIVE), bit 21 Is If the disk 
is a double density type disk and 1 
if the disk is a high densih' t\'pe 
disk. Second, you MUST set the 
drive to high density to write In 
high density and reset it tonormal 
to write normal Amiga disks, in 
particular, there are three opera- 
tions that can be performed: 
Set the dri\'e speed to double den- 
sity- 
Set the dri\'e speed to high den- 
sity. 

Eject the disk. 

The actions are performed by us- 
ing the following procedures: 



1 ) Turn off the motor and deselect 
the drive. 

2) and.b #SF8,$BFD10() 

3) or.b #operation,SBFD100 
where operation is one of the fol- 
lowing: DDSpeed=l,

4) select the AEHD drive.

drive (with the motor ofQ.

BUSINESS 



«. 



ht-'ii most small business owners decide 

Ihey need a computer, they go straight for 
the PC compatible machines. The)' overlook 
the Amiga; or if they think of it at all, games 
come to mind, along with graphics, multime- 
dia, or music programs. Tlie Amiga has a well- 
deserved reputation in these areas, but when 
most small business operators go out to buy a 
computer, they walk right past the Amiga. 
This is unfortunate, because the power that the 
Amiga brings to graphics and games can be 
used for business nccoujiting as well. 

Mo.st people st.irling up a siii.tII business 
have a big prtibleni right from the stnrt — maacn. 
There ne\-er seems lo be enough Ui do e\er\- 
thing thai must to be done. This is one very 
good reason for considering the Amiga. The 
price is low for the proces-sing power of the 
machine. The software is normally about half 
the price of comparable PC software. 
Multitasking means the spreadsheet data you 
need in that letter to the customer is available 
in one window while in another u-indow, the 
computer sorts through the customer list, 
printing out the overdue statements. 

The main reason for not considering the 
Amiga is that it is not MS-DOS compatible. 
Many of the "big name" software products.

similar to that program, and usually, some- 
thing similar is available on the Amiga, that is 
just as good, and half the price. 

If you need exactly that MS-DOS pro- 
gram, then you might consider getting an 
Amiga withoneof the MS-DOS emulators tike 
Bridgeboard or ATonce. Unless you need PC 
compatibility and Amiga features, 1 don't rec- 
ommend this action. Buying an Amiga to run 
just PC software is just not a good way to spend 
money. 



1 purch.iscd .m Amiga SIX 
computer. When my wife started her land- 
.Hcape design bii'-iiiof., we decided to usl- the 
500 for al! oLniHisine^'- purposes. Weliadtodo 
estimates for customers, letteis, accoimting, 
ad\'ertising, and record keeping, so the Amiga 
was drafted. 1 already owned most of the basic 
software, so we didn't need to buy any more. 
Now that we have been In business for a year, 
we have some experience in what to use and 
how to use it. The Amiga has been able to do 
what we need with low-cost software. 

Our Amiga sta rtcd out as a stock 500 \vith 

an A501 memory expansion and a second 

AlOlO floppy drive. It has grown since then. 

, When Workbench 1 3 came out, 1 bought the 




^./^,. 






^ftware, but did not buy the 13 ROM. I did 
nothn\'ea b.ird disl< fliL'n.iind the 1 .3 ROM did 
not do anytliiiij; to improve operation on n 
floppv-bascd system. I ha\'e added a Spirit 500 
SIN memorv expansion with 2MB of memory. 
For a while, I used (he memory expan.sion ns o 
large liAD: disk. Iwould load the entire work- 
bench disk to RAD:, then transfer con trol there. 
This system allowed me to run nio.st progrnms 
with no problems. Multitasking was not prac- 
tical with this systein. Most progrnms wore on 
separate diskettes. Then I added a Trumpcard 
500 disk controller and a Quantum 105MI! 
hard drive. By then. Workbench 2.0 was sup- 
posedl}' coming out shortly, so I still did not 
get the 1.3 ROM. 1 still usetheStarGemini-lOx 
printer that I ha\'e had even before acquiring 
the Amiga. The printer is the weakest part of 
thesystem. The type quality' is just not equal to 
that of modern printers. 

Business Application Programs 

The first programs most people get for 
business applications are a word proce.ssor, a 
database program, and a spreadsheet. Once 
along in business, you will probably want to 
get an accounting package of some kind. Of 
course, every year. Uncle Sam wants his share, 
as do state, county, and city governments. If 
youdoyourown taxes,an income tax program 
is useful. We do our income taxes using Tii.v 
Brrak from Datamax Research. 

When we started, I already owned an 
array of basic programs for personal use. For 
word processing I had cxcfllciia'l, version 2.0 
from Micro-Systems Software. My database 
needs were limited, so SuperBasc Pergonal (the 
original \ersion) was my database of choice. I 
had tried three others, and found them all 
wanting. The spreadsheet program I used 
was not geared to the wav we did busi- 
ness, so W(J had to get a ne^v one. 1 used 
Pliainr 4.0 for m\' personni accounting. 
Phasar continues to serve us in the 
business. 

Before using a computer in business, 
decide just what vou are going to use 
it for, and how you are going to use it. 
Careful planning here saves a great 
deal of trouble later, hi our case, I 
could see mvself typing estimates 
of landscape jobs, keeping a record 
of the plants bought and time spent 
on installation, sending bills and 
recording payments. What pro- 
gram will be used on each task? If 
1 don't own a program to do the 
job, what one will I buy? 

You mustalso decide how 

vou are going to save vourdata. 

I decided that 1 would set up a 

directory at the roiil level, 



called Landscape for al! the business related 
fiies. Under Landscape, 1 set up a second direc- 
tory called Clients to contain information abiiut 
each client. Under Clients is a separate direc- 
tor)' for each customer. Inside each of those 
directories we file letters, estimates, bills, re- 
ceipts, and other correspondence. This deci- 
sion affected how well the software I already 
owned worked. The spreadsheet program 1 
had could not handle this data organization. 
So far, excellence! has done well for word 
processing. We must do written estimates, bills, 
and occasional newspaper advertising. Since 
the ads don't in\-oh'eanv art work, excellence! 
is fine. We also prepare instruction sheets for 

IiThe power that the * 
Amiga brings to ■ 
graphics can be used 
for business as welj 

customers on how to care for their plants after 
we install them. 1 would go to one of the page 
processing programs if we needed any graph- 
ics, as this is not one of the strong points of 
excellence! We don't do mass mailings, so I 
have never used the maii-merge capabilities. 
So for word processing, excellence! meets our 
needs. 

Replacing the Original Spreadsheet 

I replaced my original spreadsheet prt)- 
gram with /l)i(7/i/:c' from Micro-Svstems Soft- 
ware. My original spreadsheet had one major 
problem; it could not go from directory to 
directory easily. The program did not seem to 
have any idea of the Amiga director)- struc- 
ture. It did not use anv type of file requesters. 
Since each of our clients v\'as in a different 
directory, we could not switch from client to 
client. If it had reasonable file requesters, we 
would not have had to change, ft has much 
nicer formatting than Analyze, especially when 
the spreadsheet is included in a letter to a 
customer. We use Analyze to prepare esti- 
mates for customers. We have set up a spread- 
sheet with one section lor plants and ma teria I s, 
another to summarize the materials and labor 
for the v\'hole job. The macro capability allows 
us to sivitch from one section of the estima te to 
another with no effort. 

We started the liiisiness using 
SuperBase .v- - Personal for 

any data- ,-rf!^ "«»i>.,' base needs 



.^' 




we had. Tliere weren't many. But now we will 
have to start maintaining belter customer lists, 
estimates, and billings. So we are upgrading to 
SuperBase Pwffssifliial 4. The form designer and 
programming language promise to be very 
poiverful. I will soon be setting up a database 
of past and future clients, job estimate.s, and 
bills — all related to each other. I also plan to 
put our business accounts on a SuperBase pro- 
gram. I really believe that SuperBase 4 is the 
best database program availableon the Amiga, 
or any other personal computer, as there is an 
MS-[X)S version available as well. 1 am watch- 
ing Oxxi very carefully to see what they do 
with SuperBase now that they have bought it 
from Precision SoftiN'are. 

Every business must do accounting. 
Businesses do not exist apart from their 
"books." For accounting, we use Phii/ar 4.0. 
Normally, Phasar would not be the best choice 
for running a business because it is for "cash- 
based" accounting. It records income when 
money is received, and records expenses when 
nione\' is paid out. .Most businesses run on 
"accrual-based" aecountiiig, which record in- 
come when the customerowes you the money, 
and expenses when you owe money. Most 
people (including us) use the cash based sys- 
tem \vhen they do their income tax. Phasar is 
designed for personal accounting, not busi- 
ness accounting. However, ourbusiness is very 
small, so we include the business accounts 
with our personal accounts, and our taxes fall 
rightout. Wedo not ha\-e much inventory, and 
pay most of the bills with cash or from our 
personal checking account. The few thuigs 
that we do charge, we charge on our personal 
credit cards. If the business gets much bigger, 
we may have to switch to a bigger accoiuiting 
system. For now, Phasar does the 
job we want done. We will 
use SuperBase topick up 
the areas that Phasar 
does not cover. This 
is mainly in the 
area of determin 
ing outstanding; - 
bills. 

Selecting Utilities 

.Anothergroup 
of programs that ev- 
ery business require: 
arc utility programs. They are 
the programs that vou use to take 
care o f the com pu ter a nd vou r da ta. 
The most important utility is the 
backup program. No matter what 
disk system you use, m a kc su re you 
ha\-o a regular backup procedure 
set up. 1 ne\'er heard anyone sa\', 
really regret doing that backtip.' 





72 



AmAZIiWG Co/HfUTIJ^G 



use Quai-tciimck from Central Coast Sofhvarc 
for my backups. I needed it one time a power 
failure caught my hard disk in the middle of 
write. You just can't describe the feeling of 
trying to read your business accounts and 
being lold, "Not a DOS Disk." Quarterback's 
backup meant 1 lost a dav's work, not all of mv 
data files. If CCS wants to improve Quarter- 
back, 1 would suggest either a way to back up 
from a script file or an ARexx interface, 

A disk maintenance program will also 
come in handy. This utility is very i[scful when 
vou have deleted a file by mistake. It can 
recover those flies (well, most of the time), 
mark bad sectors before you accidentally in- 
clude them in your files, de-fragment disks, 
and a host of other useful functions. I use 
Quarterback Tools for these (unctions. Some- 
times the user interface seems a little awk- 
ward, but it does the job. Again, an ARexx 
interface or the ability to run from a script 
would be greatly appreciated. 

You may be asking yourself, "Why don't 
theydo the landscapedrawings on the Amiga?" 
There are several reasons for this. First, to draw 
out the final design, we would need a plotter 
which could produce large drawings (18 inch 
by 24 inch). Such de\-ices are not cheap. Thev 
run about $.3,000 or more, equivalent to the 
price of my entire system, including all the 
software. 



Tile second reason for not using the Amiga 
for doing the landscape designs is a drawing 
program. While there are some excellent paint 
programs for the Amiga, the drau'ing pro- 
grams leave much to be desired. 1 hav'e some 
strict requirements and would not be able to 
describe a client's lot as accLiralelv as needed. 

.'Mso, I would need the drawing program 
to keep track of the .symbols used. 1 would have 
a group of symbols to represent different trees 
and shrubs. To position a rose bush, i would 
click on the s\'mbol for rose hushe.^, then place 
it in the drawing. When the design is finished, 
the computer vvould tel! me how many plants 
of each type (pine trees, rose bushes, and so on) 
1 ha\'e used. You can't believe how hard it is to 
count each plant from n drawing and get the 
same total twice. Computers count so well, 
and people count so poorly. I Available on Fred 
Fish Disk #521 is a public liomniii progrnm called 
Landscape vl.O. — Ed.] 

The program mList be able to calculate 
areas for me. VVhen a garden area is sketched 
in, hvould like the program to be able to tell me 
the area of the yard. This is necessary informa- 
Hon for figuring needed amounts of topsoil, 
mulch, and the like. 

Finally, my wife is the designer, and she 
hates computers. So shedoes the designs which 
get the customers and keep them happy. [ do 
the accounting and other computer functions. 



Of course, if ! could get an easy-to-use drawing 
program like 1 described above, 1 think 1 could 
get her to u.se it. The first time she had to make 
a major change to a "finished" drawing, she 
would appreciate the computer. 

The Amiga doesn't ha\e the wide range 
of business so ft ware that is a vail able to the MS- 
DOS computers, but there is a good selection of 
software available, tvery Amiga owner, I am 
sure, would like to see more business software 
available, just to encourage more businesses to 
tise the ,-\miga. The biggest need is for more 
and better accounting software, preferably 
aimed at specific industries. The Amiga already 
has a foothold in graphics and music. Why not 
develop accounting programs forbands, small 
recording studios, or video production shop? 
The fickl is open and ready for the imaginati\'e 
developer who sees the opportunities.

I 



roccnlly saw a demo of the 
Opciide Studiii 5 MIDI interface 
for tfic Macintosh. The Studio 5 
combines a 16 channel MIDI inter- 
face with a SMPTE converter, but 
its biggest feature is the ability to 
merge and process MIDI signals. 
It uses a graphic software inter- 
face which looks remarkably like 
Bars&PipL's Prafcssmiwl's "Create A 
Tool" feature. While the Studio 5 
is an impressi\e piece ot hard- 
ware, I kept thinking that 1 could 
do many of the same things with 
B&P Pro. This column will look at 
B&P Pro's Pipeline and "Create A 
Tool" features and explore ways 
to use them effectively in your 
music. 

Look at Figure 1, which 
shows the B&lP Pro main screen. 
MIDI data flows across the screen 
from right to left. The active input 
track is highlighted by a red ar- 
row. Data flows through the input 
pipeline to the recorder, where it 
can be recorded into thesequencer. 



and is then passed through the 
output pipeline. Understanding 
the hv D pipelines is the first step to 
using toolseffectively. Alterations 
made by tools in the first (input} 
pipeline are recorded permanently 
into the sequencer. By contrast, 
tools placed in the second (out- 
put) pipeline after the sequencer 
do not permanently al ter recorded 
MIDI data. I tend to put tools which 
split or layer MIDI data in the 
input pipeline, where their resul ts 
will be permanently recorded, 
while I place "effects" tools like 
Echo and Quantize in the output 
pipeline. Tliis setup allows me easy 
editing of "split" tracks, while be- 
ing able to tweak MIDI special 
effects in real time imtil I get the 
feel 1 want. 

One of the best ways to use 
the input Pipeline is to extend the 
usefulness of your MIDI input 
device. My Yamaha DX-7 onlv 
transmits on MIDI channel one, 
has onlv 61 kevs, and can't send 



the full range of MIDI \elocity 
values. B&P Pro compensates for 
she deficencies of my controller 
and sends a reliable, consistent 
stream of MIDI data to my sound 
modules. To use these techniques, 
vou mus t di f fercn ti ate between an 
input de\-ice and a sound module. 
If vou are using a synthesizer with 
a built-in keyboard, you will need 
to set "loca 1 off" so the synthesizer 
onlv responds to notes passed 
through the Amiga. Consult your 
synthesizer manual for details. 

For the following examples, 
\-ou should set your synthesizer 
or module to play a piano sound 
on MIDI channel 1 and an organ 
sound on channel 2. Set your ke\'- 
board or controller to transmit on 
channel I . The first technique is to 
rechanneiize M IDI input so it plays 
on a different output channel. 
Simply click on the blue number 
on the far right with the left mouse 



button and choose a new output 
channel. The next technique is to 
add a splitter, so you can play on 
two channels at a time. Select the 
Keyboard Splitter tool from the 
toolbox and place it in tl.j input 
pipeline of Track One. If you have

the Keyboard Splitter tool to move 
the split point to a different note. 
The new Velocit)' Splitter tool, 
available for download on GEnie 
and CompuServe, will allow you 
to do a similar split based on the 
velocity of the note. I generally 
use these kind of splitter tools in 
the input pipeline, because I want 
the pa rts to be recorded separa tely 
for editing purposes. 

Thus far, we've considered 
relatively simple applications that 
extend your MIDI controller's ca- 
pability. Another way of using 
tools is to build "super instru- 
ments" that use several MIDI

channels or sounds. For L'xamplL', 
instead of using the velocity split- 
ter to svx'itch bftvveen hvo sounds, 
you could combine tools to add 
organ to the piano sound when- 
ever the \-elorit)' exceeded n cer- 
tain point. (Figure 2) Or vou could 
combine the Keyboard Splitter 
with the Transpose tool so that the 
piano and organ sounds can play 
independently in the same regis- 
ter. This can be cspeciallv useful 
with sampled sounds, using oitlior 
an external sampler or the Amiga 's 
internal sounds. You can use the 
velocity splitter so that low ve- 
locity notes trigger a normal 
saxophone sound, ivhile high ve- 
locity notes trigger a squeak or a 
honking sound. The sounds can 
even be on different synthesizers, 
since the splitter sends the high 
velocity notes to a different MIDI 
channel. 

The "Zoner" Macrotool, 
which plavs on one channel in the 
loiver register, on a different 
channel in the higher register, and 
on both channels in the middle of 
the ke^■board, is a good example 
of B&P Pro's "Create a Tool" fea- 
ture. "Create a Tool" alloivs vou 
to assemble component tools into 
Macrotools, which you can then 
use in othercompositions. Look a I 
Figure 3 to see what "Zoner" looks 
iike. Open the Toolbox by clicking 
on its icon, and then select "Create 
a Tool" from the menu. Place a 
blue arrow in the upper lefl hand 
corner of the Create a Tool win- 
dow. This represents the MIDI 
data stream entering the look The 
key in building Macrotools is tt) 
route the data stream through 
various tools to a red arrow which 
transmits data on the original 
channel, or to a purple arrow 
which outputs data on a different 
channel. Add a Keyboard Splitter 
to the right of the blue arrow. Place 
a Merge In tool on the level below 
and connect it to the Keyboard 
Splitter, Then place an Delav, an- 
other Keyboard Splitter, and a 
Branch Out tool in front of (he 
Merge In (mo\'ing from lefl to 
right). Now place a Merge In on 
the third level and connect it to the 
Dela\- tool. Place another Merge 
In on the first level, and connect it 
with the Branch Out on the second 
level. Set the first Keyboard Split- 



ter to C4 and the second to C3. 
Now all that's left is to add the 
output arrows. A red arrow (pri- 
mary channel) goes on the top 
level, a plug (no output) goes on 
the second level, and a purple ar- 
row (secondary channel) fits on 
tlie third le\el.

Notes on the second level go into 
another Keyboard Splitter, w-hich 
passes notes above C3 back to the 
primary output and throws away 
theothers. Notes on the third level 
godirectiv to the alternate output 
(purple arrow). The final result is 
that notes above C4 go directly to 
the primarj' output. Notes below 
C4 are passed through the first 
Keyboard Splitter and the Delay 
tool to the secondary output. These 
notes are also duplicated by the 
delay tool and sent lo the second

notes above C3 to the primary

it allows you to change settings

from the edit menu, and the tool 
you selected will be permanently

also be applied to just a section of

Colorburst Creates Legal Fireworks 

In [he Amigii's 24-bit W.irs, one oi the 
long-awaited combatants has been having 
some trouble getting to the battlefield. The 
Colorburst 24-bit box, designed by Austra- 
lian whizkid Giir)' Ravner, is in the midst of 
some rights battles. The situation is foggy, 
since the participants nre playing things 
close to their vest while the lawyers are 
busy. From what the Bnndito has been able 
to piece togcthei' fi'oni a variety of sources, 
MAST (the distributors for Colorburst) have 
not paid Ravner any royalties. The stuns 
owed to Ravner may be quite substantial, 
but MAST hasn't released anv figures, so it's 
hard to tell. In anv case, Ravner has pulled 
the distribution rights from MAST. Perhaps 
as a consequence of this, MAST closed their 
U.S. office and left Centaur to distribute all 
their products. 

Rayner has said he's working on a new 
and much improved version of the 
Colorburst hardware and software, to be 
introduced sometime in 1992. Don't expect 
the software for the current model of 
Colorburst lo be upgraded. As to the 
capacities of this new device, we'll just haw 



to wait and see. Perhaps the added delav 
will mean added features to keep up with 
the market. Of course, we ma v be seeing 
neiv versions of DCTV and HAM-E by then, 
too. And the Bandito hears whispers of other 
24-bit card.s and boxes headed for the Amiga 
marketplace in the near future. Perhaps 
increasing competition will force the prices 
down to vvhere mere mortals can afford to 
work in 24 bit color. 

Amiga 500 Plus Gets a Minus 

While Commodore remains officially 
mum about the A500 Plus over here, it's 
causing quite a stir across the Big Ditch. 
Apparentlv, UK Amiga dealers are furious 
about the .'\.i(lil Plus. Whj', you ask, would 
they complain about a machine that's better 
than its predecessor? Compatibilit}' is the 
niiswer. You see, Commodore claims that the 
A.^OO Plus is 98"i. compatible. According to 
the Big C, they tried hundreds of games and 
only about a dozen of them failed to work, 
and almost all of those were older games. 
Meanwhile, the dealers are claiming that 
their tests only show about lO"!, compatibil- 
it\' with current gomes. Most Amigas in the 
UK are sold as game machines; this is a 
serious problem. There's no explanahon ^-et 
for the mismatch between the t^vo stories; 
perhaps the dealer.s were testing on 
machines that had a bad chip or something. 
Still, it's definitely a public relations problem 
for Commodore. Maybe that's wh^' they've 
been in no great hurry to release the .'\500 
PI us over here. 



The Bandito's Fearless Predictions 

Once again, it's Hme for the Bandifo to 
fearlessly step forward, gaze into an Amiga- 
driven crystal ball (24-bit, naturally), and 
predict what vvill happen in the new year. 
Like all good psychics, the Bandito will 
forget about past predictions thai didn't 
come true and focus on the latest, greatest 
predictions. What, you expect accuracy from 
a seer? Ho ho ho. Next you'll be looking for 
truth from a politician, or marketing 
expertise from Commodore. In an\' case, 
here are some predictions to look for in the 
coming year. 

Prediction #1 

1 ho Amiga 5U0 will be street priced 
well under S300 before the end of the year; a 
complete 1MB system v^'ith monitor will go 
for well under S500. 

This is just another step in 
Commodore's ongoing effort to rescue 
flagging Amiga hardware sales. It's a matter 
of sheer survival for Commodore, when you 
can get a complete Mac setup with a bard 
drive for art'und a thousand dollars, or a I'C 
clone for well under that. As a coroUan', you 
can expect prices to be reduced on the A2000 
line and the A3000 line. 

Prediction #2 

CDTV will be street priced well under 
$500 before the end of the year, but sales will 
still be below expectations. Good CDTV 
software will be slow in coming, and 
competition from CD-I will also hurt. 

Again, this is a move that Commodore 
has to make to keep up with the competition. 



Amazi.s'g Compltisg 



Tht' roll-out of CD-I nationwide has jlrc.idy 
Inirt CDTV, since for some rtMson Comnro- 
dore luis been slow to make CDTV n\ nibble 
.1 round the country other than in Amiga 
stores. In effect Commodore has completely 
blown its six-month lead over CD-I. Why did 
they do this? Couldn't be manufacturing 
problems, since they've had vears to work 
OLil those particular bugs. The Bandilo hears 
whispers that some of the national chains 
were won o\'er by Philips' promises about 
CD-I, and decided to wait for CD-I rather 
than pick up CDTV. The whole story may 
never be known. 

Prediction #3 

Despite rumors, the Amiga 4000 will 
not ship by the end of the vear. ^'ou mean 
you hadn't heard about this machine vet? 
Let the Bandito be the first to let you hear 
about it. Specifications are still up in the air; 
apparently, there are some vital engineering 
and marketing issues that arc still hotly 
debated at the Big C. Let's hope they don't 
argue too long, and get down to soldering. 
Still, with all the engineering talent that 
Commodore has jettisoned in recent months, 
it's hard to see how they can come out u'ith a 
new box any time soon. 

Prediction #4 

Commodore sales u'Ol continue to rise 
because of their success in Europe. American 
sales will continue to languish. The Amiga- 
only developer will be an endangered 
species by the end oF the year, as tlie\' need 
to move their software to other platforms in 
order to make decent money. 

The Amiga is still strong in Europe and 
will continue to be strong; nothing succeeds 
like success, after all. The price point is right 
for the very price-sensili\'e Euro mai'ket. The 
advent of uniform standards in the EC 
(which 1992 will bring) means that it'll be 
even easier to sell Amigas. 

On the down side, American software 
developers are increasingly discovering that 
a multiplatform strategy is the key to 
pmfitnbilit-\-. While marketing costs arc 
mucii higher in the Macintosh and PC 
markets, so are the potential profits. Any 
Amiga developers that are still around have 
to produce Mac or PC software if they ever 
want to mo\'e out of their garage and into an 
office. We've already seen some developers 
that got their start on the Amiga abandon the 
Amiga market completely. We'll see a few 
more like them in the years to come. 

Prediction #5 

The era of mass extinction for entertain- 
ment software companies has come to an 
end. This year will see no major entertain-

After a rough several years, where we 
saw companies like Mindscape, Epyx, 
Ciitenravvare, and Mediagenic take a tumble, 
it looks like the u'orst times are over. Though 
some companies arc still undergoing rough 
times (like Accolade and Softvvare 
Toolworks), it looks like they'll all pull 
through. The .shakeout has strengthened the 
industry by removing companies that 
produced lower quality games. We'll see

better ones. 



typesetting codes. It's not an easy piece of 
softuare to create, but the potential rev\'ards 
are enormous. Users arc the big winners; 
we'll finally be able to edit videotape quickly 
and easily, 

Also next year, the hardware cost for 
video editing will drop as new models of 
VCRs come out and the prices plimimet. 
We'll see many more decks that offer 
computer control, and software that takes 
ad\'antage of that control. Bv 1993, we'll see 
the Hoiy Grail of desktop video at hand: 
complete video effects, titling, animation, 
and editing in a box for less than SU1,000. 



Commodore marketing 

will enter the

will bring Amiga graphics into the '90's: 256 
colors out of 16 million in high resolution, 
upgradable to full 24 bit \'ideo with the 
addition of some RAM. This will be standard 
on the next generation of .^migas that are 
already being designed. 

Prediction #8 

We'll see more Amiga games that take 
advantage of (or even require) such things as 
faster processors, more RAM, and a hard 
drive. 

As game makers push the limits of 
current hardware, and as Amiga owners 
continue to expand their systems, this will 
ine\'itably mean more powerful games that 
require more powerful hardware. The days 
of the 512K one disk drive game will be 
history by the end of 1992. 

Prediction #9 

Commodore will announce a lavish 
new marketing campaign for the fall of 1992. 
However, once again, the effect on sales will 
he barely discernable. 

Yes, the gang that can't shoot straight 
will pull the trigger again, and as before 
they'll miss the broad side of the barn that 
houses the American marketplace. Commo- 
dore marketing will enter the lexicon of 
oxymorons, right alongside military 
intelligence and jumbo shrimp. Look, these 
guys will never get a clue on their own. Can't 
somebody out there sell them one? 

Prediction #10 

By the end of the year. Commodore will 
announce another management shakeup 
designed to boost sales. 



As a result of some of the other 
predictions, good old Irving will once again 
decide to clean house. And just as before, 
he'll have cither acted too soon or too late. 
No telling right noxv who the shakeup will 
affect or who the replacements will be, but 
look for a major overhaul of familiar faces. 

And that's more than enough predic- 
tions for now. The Bandito's crystal ball has 
overheated and shut down to prevent 
thermal damage from occurring. 

Hot Games 

Dynamix, having raided a couple of 
.Amiga magazines for hot Amiga program- 
ming talent, is making a push to create some 
cutting edge Amiga products. Current 
releases include Riac of the Dragon, Heart of 
China, and Wiilif Beami^li. If vou don't have a

hard drive, be prepared to do some major 
disk swapping; these games come on 10 
disks or so. And they've got more titles lined 
up for next year, according to the Bandito's 
sources. It's ironic that while Dynamix is 
leading the way toward more powerful 
Amiga games, their corporate parent. Sierra, 
does some of the worst Amiga games. 
Sierra's Amiga port of King'^i Qiirnt V has not 
been well received by Amiga fans. And Ken 
Williams, as the Bandito mentioned before, 
has bad-mouthed the Amiga in Sierra's 
company magazine. There's no accounting 
for this corporate schizophrenia, except to 
note that Dynamix is located in Oregon 
while Sierra is in California. Sounds like they 
don't talk to each other all that much, does 
it? 



Retreat Of The Amiga Gomes 

when the Amiga appeared in 1986, it 
represented a resolution in computer 
graphics, sound, and animation. Entertain- 
ment software companies were delighted; at 
last they had a machine that was powerful 
enough to do some really good games. The 
Amiga was far and awa\' the best possible 
machine for home entertainment software. 
And for a time, every game designer wanted 
to design Amiga games. After all, who wants 
to design for the second or third best 
computer? 

But time inarches on, and the computer 
market changed. PC clones gained a new 
color standard, VGA, that would offer up to 
256 colors at once. Sound cards came out thai 
offered some music capability f^^r i'C clones. 
Apple came out u-ith a color Macintosh. 
Hard dri\'e prices plummeted, and soon 
1 even,'one with a PC or Mac had a hard drive, 
too. And the processors got faster, and the 
machines got more standard memory. 

As the price of I'C clones plunged, they 
became widespread. Many people bought 
them to use at home, at first to bring work 
home but later to use as game machines. So 
now we come to the present day. The PC 
clone as game machine: 640K of memory, 320 
X 200 X 256 colors out of a palette of 262,000, 
12 MHz 286 or better (many games requiring 
a 16 MHz 386 or better), a 1 .2 or 1.4MB 
floppy, at least a 40MB hard drive, a mouse, 
and a sound card (Ad Lib qiiality or better), 
with manv sound cards using digitized 
sounds or speech. This is the minimum 
hardware standard now for games. .NJext 
year you can expect to see many games 
requiring 1MB of memory and better

processors. Some will even require 2MB of 
memorv; somo may iise 640 \ 480 x 236 color 
graphics. 

While the PC clone has undergone this 
advancement, what's happened to the Amiga 
as a game machine? If you're talking about 
the lowest common denominator of Amiga 
(which is what game designers have to shoot 
for), it's barely changed at all in since its 
introduction in 1985. The graphics mode 
used for almo.st all Amiga games is still the 
same: 320 x 2110 x 32 cokirs out of 4096; 
sometimes 64 Extra-H.ilfBrite colors, and in 
one or two cases you have HAM mode. The 
base model Amiga 500 has 51 2K of memory; 
it's usually IMB or more in the American 
market, but since that's a small part of the 
total you have to design for the European 
standard. (Grndually, the Euro.sare heading 
toward a 1MB minimum, but you'll still lose 
a lot of sales if your game can't run in 512K.) 
The base CPU is stiil the same old 7.13 MHz 
68000; the bulk of the game market (again in 
Europe) doesn't even know how to spell the 
word accelerator, much less pay for one. The 
disk storage is still the same 880K floppy, 
and you certainly can't count on the Amiga 
owner to ha\'e a hard drive. The one bright 
spot is Amiga sound; although it hasn't 
changed since the Amiga's introduction, it's 
still better than anything available on an IBM 
sound board . 

Comparing the PC clone game machine 
to the Amiga game machine, the Amiga 
comes up short. The PC clone has a much 
faster CPU (even allowing for the Amiga's 
blitter), more RAM, the certainty of a hard 
drive for much greater storage capacity, and 
better graphics.

So now the Amiga is the number 2 
game machine on the market. Who would 
ha\e thought it possible? And it's all 
Commodore's fault for having done 
absolutely nothing to improve the basic 
hardu'are. What do we have to show for 3 
years of Commodore dc\'c!opmcnt of the 
Amiga? Three new case designs after the 
A1000; a new bus specification or two; and 
some faster CPU's. This is progress? 

In the US, a good seller on the IBM is 
511,000 units; on the Amiga, it's 10,000 units if 
you're lucky. The only thing that keeps 
games coming out for the Amiga is the 
European market, where you can expect to 
sell 25,000 copies of a good game. Still, you'd 
sell more copies of an IBM game overall; 
perhaps twice as many, even more if it's a

big hit. The best Amiga game these days will 
hit perhaps 40,000 units worldwide; a smash 
on the IBM can do 1 50,0011 or more units. 

So by doing IBM games, you get to 
work with more colors, a more powerful 
CPU, and a hard drive (for lots more 
storage), and you know that you'll sell more 
copies. Is it any wonder that games now arc 
being developed on the IBM and ported to 
the Amiga? The only wonder is how long 
developers will continue to port to the 
Amiga, if game sales don't increase more. 
Already some de\'elopcrs don't even bother 
to do Amiga versions of their games. 

What can be done? Well, it's time for 
Commodore to impro\'e the basic Amiga. 
Yes, the Amiga 500 and 2000 lines need an 
overhaul. What could make these machines 
competitive without raising the price? Well, 
start with the CPU, for one thing. In the

quantities that Commodore buys, a 16 MHz 
68000 costs only a few pennies more than an 
8 MHz 68000. And Motorola would be more 
than happy to dump 6S020's off at a price of 
only a dollar or two more than that. A 16 
MHz 68020 would give the base Amiga a 
much-needed performance boost. While 
you're in there under the hood, let's do 
something about the chip set. At the very 
least A500's should ha\'e the ne«' Denise and 
Agnus, for a flicker-free mode and 2MB of 
Chip RAM if you want it. Better stiil, finish 
engineering that new 8-bit chip set and put it 
into all your Amigas. Now, drop the price of 
an add-on 40MB hard drive to $300 list price; 
make sure that included in its case is at least 
one expansion slot, a hceficr power supply, 
RAM expansion, and a slot for a new CPU 
card. The A2000 line could use the same base 
changes (but perhaps with a 68030 instead), 
though you should keep the price at $999 
WITH a 40MB hard dri\'e built in. Oh yes, 
make sure the base RAM is 2MB. The sound 
chip can stay the same, though if you want to 
impro\'e things why not put in two of them? 

If the A500 had those specs at a retail 
price of S499, it would be a damn good deal. 
An A2000 with similar specs but a 68030 
CPU at S999 would bo an even better deal. 
And that's what's needed to make the Amiga 
a viable computer in the American market. 
So what are you waiting for. Commodore?

Fantastic Voyage 



by Tim Duarte 

Fiuittiftk Voyage, a ni.'U' shoot 
'em up from Centaur Software, is 
based upon the 1966 20th Century 
Fox science fiction movie. After 
boarding the Proteus, an experi- 
mental submarine, the Combined 
Miniature Deterrent Forces 
(CMDF) shrink you and your sub 
down to microscopic size. Then, 
you are injected into the blood- 
stream of a criticallv ill patient 
suffering from a blood clot in the 
brain. It is your mission to guide 
the Proteus to the blood clot and 
destroy it ivi th a laser gu n. No one 
said this would be an easy task. 

Fantastic Voyage(FV) is quite 
a challenge. There are three levels 
to conquer, with the blood clot 
ending the third level. Along your 
wav to the brain, the Proteus is 
attacked by numerous opponents 
because it is regarded as a foreigr\ 
invader to the patient's body. 
Shoot the red blood cells, white 
blotvd cells, cancer cells, and all of 
Iheotherobstaclesforpoinis. liach 
time your ship collides or makes 
contact with any of these, your 
protective shield is ^^'orn down. 
When the shield's energy level 
reaches zero, you lose a ship. 
Shooting three opponents in a rou' 
slowly regains the shield's energy. 

1 found my energy lewl de- 
creasing much too quickly. .A 
blend of defensive skills and 
dodging the opponent helped in 
o\'erconi ing eac h group of a ttack- 
ers and keeping a reasonable 
shield energy le\'el. Also, FV docs 
not require the player to destroy 
each altacker in the group — you 
more or less shoot what you can 
and try to su r\ive. Also, makesure 
you don't run the Proteus into the 
surrounding walls, or it will crash 
and vou'll lose a ship. Along the 
wav, you'll come across fuel and 



oxygen cannisters. You'll lose a 
ship if the fuel and oxygen gauges 
run em p ly , so pick th esc u p when 
you can. Other times, vou'll come 
across va rious weapons which will 
he necessary in order to destroy 
certain opponents. Scattered 
throughout the three le\'cls are 
nine circuit board pieces. All of 
these pieces are needed and re- 
quired to operate the laser gun 
when you reach the brain, level 
two is packed with atomic oppo- 
nents such as protons, quarks, and 
other particles. In level three, travel 
through the nerve netv^•ork of the 
brain, as you close in to \'our tar- 
get, the blood clot. 

FV comes on two disks, and 
the manual docs not mention any- 
thing about hard disk installation. 
However, thegameasked for only 
one disk swap, so there are no 




headaches here. Leave that hard 
disk space for your other applica- 
tions and programs. Hie game re- 
quires 51 2K and a single disk drive, 
so there's no need to place t!ie 
game on a liard drive. FV loads 
from the disk quickly and has a 
beautiful, haunting musical 
soundtrack in the introduction of 
the game. The intro reminded me 
of watching a mtivic as the pro- 
duction crew's names ran across 
the screen as the credits do in a 
movie. Unfortimately, 1MB of 
CHll' liAM is needed for a musi- 
cal soundtrack to play during 
gameplav. After playing FV on a 
standard A2000 without music, i 
tried it on a 3000 with stereo 
speakers and found the game 
much more enjoyable with the 
musical soundtrack. 



Centaur planned well; there 
are PAL and NTSC versions of FV 
on the disk. With this packaging 
technique. Centaur can excel in 
the European Amiga market as 
well as the North American mar- 
ket. The manual contains instruc- 
tions in English, German, French, 
and Italian. Tliree difficulty levels 
arc available to choose from: Be- 
ginner, Advanced, or Pro. The dif- 
ference among the three le\ els lies 
in the number of times the Proteus 
can be hit before you lose a life. I 
would like tosee a Children's level, 
but 1 suppose e\'eryone would 
choose this level and take the easy 
way out. Beginner mode is very 
demanding, but I accidentally 
discovered that 1 gained 40 or so 
li%'es by hitting the S ke\-. FV also 
allowsn "continue game" feature, 
something that is con\'enient for 
those game sessions when voii 
want to see if you can get just a 
little farther in the game. F V a II o ws 
you to continue only a lew times, 
though. One annoyance i\as that 
sometimes when I lost a ship, I 
was returned to the beginning of 
the le%'el and forced to face the 
opponents 1 had just recently de- 
stroyed minutes ago. Apparently, 
there'sa certain point incach level 
you must reach, or you'll ha\'e to 
destroy or avoid thosenastics once 
again . It's a minor annoyance that 
va nishes once you become ski II f ul 
at mastering the game. 

The game is a first-class 
program, and can provide hours 
of enterta inment. The graphics are 
detailed and were based upon 
actual microscopic pictures of the 
bods''s various tissues. Since the 
game's color fading features are 
fairly dark, the manual recom- 
mends piaving FV with the lights 
out for more effect. Dim the lights, 
gel yourself a comfortable chair, a 
reliable joystick, and ciimplcte that 
mission. 



Big Business 



bif L. S. Lichtiiiniiii 

The games Bifi Btis/»fss and 
lVi?//.-:(riV/, sold together as a single 
package labelled simply Big 
Business, allow a single plaver or 
multiple players to try their hand 
at outmaneuvering competitors 
and turning a large company into 
a humongous company, or mak- 
ing a million dollars managing an 
in\estment portfolio. 

In Big Business, three com- 
panies vie in amassing \'ast 
quantities of money by selling 
products which must they make 
themselves out of three appropri- 
ate raw materials. In addition to 
ensuring an adequate supply of 
ravv materials, by manufacture or 
purchase on the Commodities 
Exchange, budding corporate 
managers must set production 
rates, build additional factories if 
necessary, and decide how much 
money to spend on research and 
development, how much to spend 
on advertising, and aboveall, how 
much to charge for the product. 
Since Big Business is intended to 
be a rea I istic experience, company 
executives also have the opportu- 
nity to give competitors grief by 
filing nuisance lawsuits, engaging 
in industrial espionage, causing 
labor trouble, and making take- 
over bids. 

Big Business is plaved as a 
fixed length game, against the 
clock. 1'he period of competition 
is set from 1 to4years(eachoffour 
fiscal quarters, i.e, four turns) 
when the game is started. Each 
player is gi^'en just three minutes, 
or six in a novice game, to review 
the company's financial situation 
and implement the necessary 
bLisiness decisions for the present 
quarter, in between quarters sales, 
figures are posted, and a list of 
random news items delivered, 
some irrelevant and some highly

significant, as when you are in- 
formed your factory has burned 
down duo to n fire extinguisher 
sign sliorting out. 

Big Business can be played 
alone against the computer, but 
wi II bo m uch more in teresting «■ 1 1 h 
more than one human player, 
\vhen its full potential for dirtv 
tricks can be realized. The com- 
puter players arc fairly 
unaggressive. Bidding for raw 
materials on the commodities e.x- 
cliange, for example, is much more 
exciting when you ha\-e to worry 
about a \\'ell-hecled human op- 
ponent continuallv upping your 
bids and cutting von out of the 
market for a raw material you 
desperately need to meet your 
production schedule. 

No effort has been spared to 
make Big Busines.s low-humorous. 
For starters, you are given your 
choice of product, ranging from 
baby food (manufactured from 
pork fat, cobalt, and strontium- 
yO) fo paintings (pa int, canvas, and 
numbers). Then there are your 
executives, through u'hom you 
must execute your business deci- 
sions: the Financial Officer, Jane 
Dough, etc. The game is played 
from a set of gadget-controlled 
screens; the main screen, for in- 
stance, is a staff meeting in }'our 
executive boardroom, and 
changes from quarter to quarter in 
ways which reflect how your 
company is doing. Similarly, you 
interact with your Marketing Of- 
ficer in a bar. Be sure to follow the 
manual's suggestion and, if nec- 
essary, waste a game clicking on 
the various objects In the different 
screens. The sound ef fects arc also 
very impressive and amusing. 

Wallstreet is mucli more so- 
ber. The objective is to turn a small 
pot of nxoney into the largest one 
possible by making appropriate 
"investments" with thecompuler. 
Up to four people may plav,but as 
success can be gauged directlv by 
the dollar value of one's portfolio 
at anv moment, theeomputer does 
not fill in for any missinghumans. 
Competition is strictlvyouagainst 
the market. 

The game is played in a series 
of "rounds" of invcstmentactions, 
with tlie number of rounds being 



adjustable from 1 to 99 at the start 
of each game. Before each round, 
one is presented with one or more 
"market bulletins" xvhich may 
suggest how the value of \'nrious 
investment options will be 
changing in upcoming rounds. For 
instance, a news report of a 



program locks up irretrievably. 

As for Wallstreet, fornogood 
reason I can imagine, a time factor 
is introduced into investment 
transactions. The time one is a 1 lot- 
ted to make transactions is also 
%vildly \'ariable, from theabsurdly 
short to the pointlessly long. Ex-

looming strike in the auto indus- 
try' may tip you off to dump your 
automoti\'estocks. Aside from the 
50 stocks whose behavior is mod- 
elled, the players have the option 
of investing in a Simula ted mutual 
fund splitting the dollar value of 
the investment between 20 blue 
chips, in foreign currency, in gold, 
in fixed-interest-rate .securities, in 
bonds, or in a mundane interest- 
producing savings account. One's 
stake ma\' be split in any way cfe- 
sired between any or all of these 
investment options. 

The standard initial stake of 
$5000, bv the way, may be lipped 
by participatinginan "investment 
knowledge" quiz before the start 
of the game. Correctly answering 
a series of questioiis on financial 
terms allows a player to increase 
his or her pot of cash by up to a 
factor of 1 0. The correct answers to 
these questions all seem to be 
contained in material accessed by 
using the information menu from 
the investment bulletins, 
VVallstreet's concession to 
educahon. 

Novvforthebad news. While 
I've had a lot of fun with these 
games,neitherone is what I would 
consider a properly finished 
product. Big Business allows sav- 
ing games in progress; imfortu- 
nately, after restoring a saved 
game, the graphics and sound 
misbehave and eventually the

haust your time in making a buy, 
and you uon't be able to sell any- 
thing the sa me round — to the vast 
detriment of realism. 

Also, I'd swear the program 
simply doesn't calculate the value 
of gold investments correctly in 
portfo 1 i o reports. The informa tion 
on financial terminology buried 
in the program would have been 
interesting, if it weren't for the fact 
that the explanations are some- 
times more obscure than the 
original jargon. 

For both these games, the 
manuals are so cheaply prodiiced 
as to be embarrassing. The Big 
Business manual at least seems to 
beaccurate, but that for Wallstreet, 
besides being unfaithful to the 
game in places {e.g., there's one 
investment option in the manual 
v\'hich doesri't seem to be in the 
program), is frequently terse to 
the point of uselessness, and both 
it and the game seem to contain 
terms which 1 suspect didn't suc- 
cessfullv make the transition from 
the German of their origin to the 
English of tlieir point of sale. 

I find it hard to recommend 
either of these games despite their 
good poiiits, Buvers of software 
paying commercial prices have a 
right to demand better. Owcal 
emptor. 



Altered Destiny 



by L S. Lkhlmann 

Been out of touch for a few 
)ears and curious as to \vhat the 
old Infocom text adventures might 
ha\'e mutated into? Accolade's 
Altered Destiny is a good intro- 
duction to the state of the art in 
adventure gaming. 

Altered Destiny (AD) main- 
tains Accolade's usual high pro- 
duction standards. The game 
package consists of manual, 
Amiga instruction card, a "travel 
diary " and map poster previewing 
some of the weird places you will 
be going and strange people you 
wUl meet, six copyable Amiga 
floppies, and a free clue book. 
There'salso a sec retdecoder wheel 
of the type Accolade has been us- 
ing of late as its sole copy protec- 
tion. Fortunately, in view of its 
massive size on floppies, AD can 
be installed on a hard drive, and 
comes with its own installation 
utility. 

What's it about, you ask? 
Well it's about a man who ... ah, 
no, better to sav that it's about a 
crisis in . . . actually, AD is a bit 
harder to describe than most of 
these ad\'enture games. Let's be-

himself tlirough a fantasy world 
while clothed in pajamas and 
storting from approximately zero 
information <ind without. my good 
analogies from classical fantasy to 
guide him. (Beginiiing to wish 
you'd stuck u'ith Tlw Bard's TaJt:'!) 
Indeed, Daltere seems to liave es- 
sentially nothing in common with 
any other fantas)- 1 have encoun- 
tered before, a condition which I 
find one of the ga me's most attrac- 
ti\'e points. 

I don't pretend to be an ad- 
venture game wizard, but I still 
have to say that I think AD is !umi. 
Those who put the cl ue book in the 
drawer are probably in for a long 
period of fairl v a i m 1 ess wa ndering 
before specific tasks useful to the 
overall quest begin to present 
themselves. Bo prepared to visit 
and re-visit many places. Be pre- 
pared to drop things for later 
pickup — P.J.'s pajamas appear to 
be very short on pockets. Be pro- 
pared to do highly non-obvious 
things. If something looks odd or 
t)ut of place, it's generally very 
significant. 

AD is extremely aggressi\e 
in its use of graphics and sound. 
ruU-screengrapliicsareemployed, 
the intermittent need for text input 
(or functions such as game saving) 
being handled in interaction boxes 
that pop-up o\'er the screen ivhen 
the appropriate keyboard or 
mouse actions are taken. The ani- 
mated figure representing our hero 
is moved around the screen with 
pointer and mouse or the arrow 
keys. All the screen backgrounds 




are animated, and many have their 
own musical scores. The artu'ork 
itself isbeautiful, fully up to Amiga 
display standards, which until re- 
cently many games of this type 
have not been. Indeed, the 
graphics are perhaps a bit beyond 
Amiga standards; many of the 
screens give indications of the 
improvement that more on-screen 
colors would bring. Everj'thinghas 
its price. The \vorst thing about 
AD is undoubtedly its speed. The 
wait between screens soon gets 
oppressive pretty fast — all that 
animation apparently takes a lot 
of time to set up because very I ittic 
of that wait is hard disk acce.ss. I 
don't know how AD plays off flop- 
pies, and I'm not anxious to find 
t)ut. I expect that life in Daltere 
would be a lot nicer foi' those with 
an A3000 or a 32-bit accelerator 
card. 

My other little whine is about 
the interface. In the rich graphical 
en\-ironmentof AD, most liKntions 
have a whale of a lot of stuff which 
might bo important. It's pretty te- 
dious to have to try to inspect ev- 
erything which might be mo\eable 
to find out if it actually is, but in 
.-XD there's noalternative.lt would 
be very nice if there were some 
sort of point-and-click arrange- 
ment for checking objects, a la 
ICOM Simulation's interface for 
its Shmiowgatc and Deja Vu. The 
mouse method for moving P. J. 
would have to be eliminated, but I 
tliink that would be small lo.ss, as I 
found it slow and not at all up to 
the fine control of movement 
\vhich is often needed. 

Quibbles aside. Altered Des- 
tiny is a tour de force in the com- 
bination of art, music, and story. I 
don't think any game I'\'e seen 
since Defender of tJie Crown has 
made such an impact on me \vith 
its sounds and sighl.s. Adventure 
gamers take note.

s Challenge 



by M(V(,f/ E. Millet, Jr. 

Alas, poor Chip is a nerd. 
Not just any nerd, but the nerdiesl 
of the nerds. So imagine Chip's 
delight when Melinda the Mental 
Marvel, a computer nerd, says he 
can join her exclusive computer 
club if he can pass the entrance 
exan^. The exam entails working 
through 144 levels, all of which 
invoh'e sol ving maze-like puzzles 
of increasing difficult^'. You can 
accept the challenge, and help Chip 
to \vin Melinda over, or you can 
doom him to an existence as a 
nerd . Which will it be? 



vou may be able to use to vour 
advantage as well. The strategy 
for each level is a little different, 
and requires both planning and 
trial and error to o\ercome. 

Chip is moved about with 
the joystick, while the keyboard is 
used for various features such as 
pausing the game and turning the 
music and sound effects on and 
off. Although a game in progress 
can't be sa\'ed, at the end of each 
level, a code is given so that you 
can restart the game at that le\el — 
just don't forget to write it down! 
The one-disk game is copy pro- 
tected, using a black ink on black 
cardboard codeivheel from which 
you must enter three different 
codes at the beginning, and occa- 
sionally in the middle, of the game. 




If you like mazes, vou'li en- 
jo vC////!'.-.C/irt//c;(^\;('. Your goal is to 
maneuver Chip through various 
mazes, in the time alloted for each 
le\'el. The le\'eis are progressively 
more difficult, and offer man)' ob- 
stacles to o\ ercome before a level 
can be completed. Most levels re- 
quire Chip to collect a certain 
number of chips, which is shown 
on the right portion of the screen 
along with the time remaining, the 
current le\-el, and an inventory of 
items collected on that level. Once 
enough computer chips arc col- 
lected, tiiey can be plugged into a 
special socket which gives Chip 
access to the next le\el. 

Part of the puzzle is finding 
the chips, while on many levels 
getting to the chips is the next 
portion of the puzzle. Completing 
a maze often requires thecollectiiin 
of various keys and accessories in 
order (o overcome obstacles such 
as ice, fire, force fields, and ra\'- 
enousbugs. Invisible and recessed 
walls often impede your progress, 
as do b locks of movable d i rt v\'h i ch 



Game graphics and sounds 
are above average, bLit the game's 
main feature is gameplay. Al- 
though the plot may seem juvenile, 
the actual mazes are fun and 
challenging. The first fcvv levels 
are introductory in nature, giving 
you a feel for \vhal you'll encoun- 
ter later on. Many of the levels take 
a lot of though t to complete, wliich 
keep the game interesting. Al- 
though therearesome areas which 
require you to move the character 
quickly through his paces, the 
majority of the game invol\'es 
creating and executing a plan of 
attack \vhich will allow vou fo 
achieve your goals. 

Chip's Challenge is quite fun 
and stimulating, and you may find 
yourself losing some sleep as you 
trv that last level JList one more 
time. .Although a bit pricey, the 
game does offer many hours of 
entertainment. If you're into 
mazes, get \'ourself in and out of 
Chip's Challenge.

King's Quest 5 



by Miguel E. Millet, jr. 

Life in Davontry has alvvavs 
been dif ficu 1 1 for Ki ng Cira liani a nd 
his family, in one form or another. 
There u'as always some trial or 
tribulation which had to be over- 
come, but for once Graham felt at 
peace with his world. The kingdom 
was prosperous, his subjects happy 
and healthv. Unfortunately, his 
good fortune wasn't to last very 
long. The King ^'entured forth for 
a short walk, and when he re- 
turned, his castle and all of its oc- 
cupants \vcrc gone! Whatever he 
was up against, it surely was 
someone or something of great 
power. But he had no choice — 
Graham had to go in search of his 
family, and release them from 
bondage! 

Thus begins King's Quest 
subtitled "Absence makes the heart 
go yonder." The pla^■er assumes 
the role of the handsome King 



move Graham around, you place 
the travel icon where you want 
him to go, and click the left mouse 
button. To get an object, you 
change the cursor to the action 
icon, and click the left mouse but- 
ton over the object you'd like to 
grab. The Interface in\'olves no 
typing, and allows the player to 
concentrate on solving the multiple 
puzzles throughout the game. 

The game is well constructed, 
although the graphics shown on 
the rear of the package reflect the 
IBM screens. The Amiga graphics 
are done in 32 eolors.and arc fairly 
good, but not spectacular. The 
music and sound effects are ex- 
cellent, making you feel as if you 
were actually tra^'eling through 
the terrain that Graham is. Unfor- 
tunately, things move slowly on a 
stock Amiga 300/1000/2000, de- 
spite increasing game speed and 
decreasing game detail. Using a 
faster machine should provide 
better performance. 

Provided on eight disks, the 
game uses a code look-up form of 



Monty Python's 
Flyiiii 



ig Circus 




Graham, on his quest to free his 
family and restore his kingdom to 
its former glory. Your only Help is 
a cowardly owl named Cedric, 
who will accompany you on your 
\vay as long as the going isn't too 
tough. The challenge is not only to 
free your family, but to help as 
many others as you can along the 
way. 

The parser for this adventure 
game is gone. It's replaced by a 
completely mouse-driven inter- 
face which works fairly well.Thero 
are several different cursors made 
available by pressing the right 
mouse button. These cursors in- 
clude a tra\-el icon, a look icon, an 
action icon, and a talk icon, all of 
which alloiv you to perform func- 
tions similar to their names. To 



copy protection wliich pops up 
occasionally during the game. 
Thus, yi'u'll ha\'e to keep the .^5- 
pnge manual nearby. The game is 
easily installed on a hard drive, 
occupying about 6MB of space. 
Running the game from a hard 
dri\'c increases the speed of 
gameplay, and is highly recom- 
mended. 

King's Quest 5 is definitely a 
family adventure, offering a chal- 
lenging adventure along tvith ex- 
cellent sound effects and amusing 
animations. The game is fun and 
interesting, and will offer many 
hours of enjoyment to all. King's 
Quest 5 is definitely the best in- 
stallment of the series, but is a 
great game even on i ts own. Highly 
recommended. 



b]/ Miguel E. Muki, Jr. 

And now, for something 
completelv different. ..Hou- would 
\ou like to pla\' a game that is part 
quest, part adventure, and totalh' 
strange? Let's rephrase that. How 
would vou like to go looking for 
parts of vour brain that are being 
held for ransom, with the ransom 
being tins of Spam ham which you 
must collect, all the while defend- 
ing yourself from pieces of meat 
by throwing fish at them? If that's 
not clear, mavbo vou should read 
the ins true tion manual , ti tied "The 
Official Hungarian Phrase Book — 
Completewith Dance Steps." Well, 
it's time for something completely 
different. ..it's Moiih/ Pi/Huni'f Fli/- 
iiig Cirais! 

\'irgin captures the flavor of 
thee.\tremGlv sillv "FlvingCircus" 
of old. In the game, the best 1 can 
figure out, you control Mr. D.P. 
Gumbv, the old cartoon character 
from the show. It seems that Mr. 
Gumbv has had his mind ab- 
ducted, and split into four pieces. 
Each piece can be retrieved for 16 
cans of Spain, after which Mr. 
Gumbv can become a whole hu- 
man cartoon character once again. 
Gatheringthc necessarv ransom is 
your quest, but nobody said it 
\i'ould be easy. 

As Gumbv, you lra\el 
through the cartoon world of 
Monty Python's Flying Circus, 
encountering the strangest adver- 
saries ever to inhabit a computer 
game. Flvlng feet, pieces of ham, 
puffcrfish, exploding kitties (yes, 
even exploding kitties), and vari- 
ous human organs attack you as 
vou move about in search of Spam. 
Of course, your bod\' changes to

environment you are currently in. 
Thus, you start out as a fish. 

You are gi\'en three lives to 
explore the four \'er\' strange le\'- 
ols found in the game. The quest in 
each le\'el remains the same, al- 
though the environment may be 
different. The joystick controls 
yourcharacter in the usual maiiner, 
up is up, dovkTi is do wn, etc. Press- 
ing the fire button fires your only 
weapon - a dead fish (at least I 
think it's dead). You'll lose points 
for hitting the eiiemv, but (hat's 
gtiod — the los\er your score, the 
better yoii're doing. Your score 
slartsal 99,9y9,9y9, and goesdown. 
A new life is rewarded for every 
10,000,000 points you lose. You 
can't save a game in progress, so 
once you have lost, you start from 
the beginning. 

Game graphics are fairly 
good, with appropriate .sound ef- 
fects. You can either have the 
"FIving Circus" theme song play 
in the background, or switch to 
just sound effects. There is no 
provision for turning the sound 
off, or to pau-se the game. The game 
scrolls smoothly, and the joystick 
is quite responsive. Much like the 
original show, your progress is 
often interrupted bv various vi- 
gnettes, usuallv havingsomething 
to do with trees. The manual is 
hilarious and well worth reading, 
but isn't meant for youngsters. 

Montv i'vthon's Flying Cir- 
cus is strange, but extremely fun. 
The game has an addictive nature 
that keeps you playing, justso you 
can sec what weird thing will 
happen next. If you're a Python 
fan, you'll get hours of fun out of 
this one!

Battle Chess 11: 
Cliiiiese Chess 

by Miguel E. Millet, jr. 



The game of chess is literally 
several hundred years old, origi- 
nating in India but spreading 
rapidly throLighoiit the rest tif the 
world. Although there is now one 
formal, international formof chess, 
there have been many different 
variations of the game that have 
existed through the centuries. In- 
terplay noiv challenges you to a 
game of chess, not any old game of 
chess,butChineseChess. The goal 
is still to checkmate vour oppo- 
nent, butyou'll haveto rclearo the 
pieces, and rethink your chess 
playing strategics. Are you ready 
for Battle Oicff 117 

BattleChes.s II; Chinese Chess 
is the sequel to the popular Battle 
Chess, introduced several years 
ago by Interplay. The "Battle" 
name comes from the fact thn t once 
pieces are moved, they actually 
have a small battle on the screen 
for the position they will occupv- 
Of course, the playerahvays knows 
which piece \\\U win, but the pieces 
are destroyed in such marvelous 
wavs that is often fun to just v\'atch 
the pieces as they destroy each 
other. 



Chinese Chess varies from 
rcgularchossinsevora! ways. First 
of ail, there is a prominent river 
which runs down the center of tlie 
board, separating the two sides. 
Most, but not all, the pieces can 
cross the river to fight the enemy. 
Pawns are not promoted, should 
thev reach thefarcnd of the play ing 
field. Another variation in the 
pi a ving field is tha t i t is made up of 
points, rather than the squares 
found in con\entional chess. 
Lastly, there are the two "Imperial 
Palaces," located at the far ends of 
the plaving field. Tlie King and 
Counselors can move only ivithin 
these nine points. 

Once you have overcome the 
difference in playing fields, you 
must examine the new playing 
pieces. Each side has one king, two 
counselors, two ministers, two 
knights, two rooks, t^vo cannons, 
and five pawns. Each of these 
pieces has its own possible mo^'cs 
«'hich are different from those 
found in regular chess. Reading 
the manual, as well as watching 
the computer plav a few games 
against itself, is highly recom- 
mended in order to learn both the 
movement of pieces and potential 
strategies. 

Chinese Chess becomes an 
acquired taste much like the 
regula r ga me of chess. What helps 
the piayer through these tough 
periods are the amusing anima- 
tions. 

Like its predecessor. Battle 
Chess II features animations rep- 
resenting the struggle between 
pieces. Even though you knou' 
-which piece will prewiil, it is fun 



and amusing to watch a pawn be 
destroyed by a cannonball, or a 
knight destroyed by a rook. There 
arequitea few laughs inju.st watch- 
ing the pieces fight it out. The ani- 
mations are shortbut effect! ve, and 
greatly enhance gameplay. Over- 
all, the graphics are fairly well 
done, but not spectacular. Sound 
effects accompany the mo\'ement 
of pieces, as well as the battle se- 
quences. 

The game has numerous fea- 
tures, including play via modem 
with another Amiga or IBM. Play- 
ers can save a game in progress, 
and can set up the board in any 
way desired in order to play out 
different strategies. There are 
many different playing levels, so 
even the mostno\^ice players stand 
at least a fighting chance. Tlie com- 
puter can offer hints, as well as 
allow you to take back a move. 
Game pieces are moved using the 
mouse. Despite what the manual 
says, there are a few key-board 
shortcuts to access some of the 
menu items. The game is easily 
installed on a hard drive, as the 
disks are not copy protected, but 
the player must type in data from 
the manual at a random time dur- 
ing gameplay. 

0\'era 1 1 , Ba ttle Chess II offers 
a refreshing change of pace from a 
regular game of chess. Learning 
how the pieces move is fairly pa in- 
less, but learning the strategy be- 
hind the game can be quite a chal- 
lenge. If you enjoy a good game of 
chess, you'll enjov Battle Chess II.

The reason that our reprcscntati\'e

From experience, v\'e know meinorv-

a memory conflict. This is a standard 
suggestion we offer when we hear of an

that vou might be able to help me get in

A check itf AC's Guide, Wiult-r '92. shows thiU

Well Toasted Musician 

Like Barry Wais, I was dismayed by 
the short shrift gi^'en Music-X by Phil 
Saunders. I, too, am a satisfied Music-X 
user who is pained that the program has 
been written off by the Amiga press. I 
talked to MicroFllusions, who told me that 
there is an update of Music-X in the works. 

While 1 may not be delighted with the 
content of specific articles, I would like to 
thank AC for recognizing that music is one 



of the creative applications of the Amiga. 
Not being into \'ideo, I'm pretty well 
Toasted out. Thanks again for providing 
regu la r m usic ct) verage. 

Ruth H. Kacztnarek 
Woodridgc, IL 

In his reply in part to Barri/ Wais's criticism, 
Phil Saunders wrote in his December '91 
column: "While Music-X has some nice 
features, it has.. .known bugs that have not 
been fixed in over a \/air. I! also reportedly 
does not run under AmigaDOS 2.0. 1 would 
fmd it difficult to recommeiid...Music-X under 
these circumstances. " It sounds thai Phil 
Saunders' position is that the year-old bugs 
need to be removed before he endorses Music- 
X — not quite a "loriling off by the Amiga 
pre.^s." we zronld judge. 
You 're having your nntsic interest fueled in 
this issue, Ruth; look at tlie expanded coverage 
and enjoy! — Ed. 



A Canadian Concern 

Why have you not seen the vision of 
addressing the needs of Canadian Amiga 
users? jtist think of the vast number of 
educational institutes, TV stations, and 
small office users who hunger for some- 
thing new and exciting. More exposure 
should logically bring about an increased 
buving market for your product and those 
companies which support it. It seems to me 
that there is a potential market for, say, a 
70"',, Canadian bi-monthly magazine for the 
Amiga worid up here. 

Right noiv, we discover only 
accidentally Canadian suppliers and 
developers of Amiga-related hardware, 
software, and peripherals. While on the 
subject, let me ask vou whv you cannot 
quote prices in ads in both U.S. and

trouble deciding hou' much to send to 
mnil order compiinies, developers, and to

Ill another m.itler, couldn't you 
publish an over\'ievv article or serie.s in 
which vou outline the differences among 
such languages as C, PASCAL, Modula-2,

program having the same fuiiction in each

Also could Amiga Vision be used to 
produce a seminar outline and demonstra- 
tion of a company's product, a departmen- 
tal guidelines manual, or an illustrated 
Bible storv? If so, what supporti\'e 
programs coLild provide the data input for

Perfect Pages 

How to produce PosfScripf-quatify pages without 
buying a PostScript loser printer. 

By joe Viiliicirn 



Okay, so you finailv have that desktop 
publishing program you've been longing 
for. You're creating dazzling pages in full 
color on vour Amiga, and dreaming of the 
big time: publishing your own gloss)', na- 
tional circulation magazine from \our stu- 
dio. 

Then j'ou try printing your pages on 
your laser or dot-matrix printer, and it hits 
you; without investing in a PostScript laser 
printer, which will cost sc\'era! times the 
price of your Amiga, you ivon't be able to 
print those beautiful PostScript files created 
on your DTP program. It's that simple. 

Or is it? Actually, there are vvaysarouml 
the PostScript dilemma. First, however, voti 
must determine it you really need PostScript 
output. 

If your interest in desktop publishing is 
recreational, or if vou intend to use it to 
produce an occasional newsletter or busi- 
ness report, you probably don't need a 
PostScript printer. The latest versions of the 
three big Amiga desktop publishing pro- 
grams — Professional Page 2.0, Saxou Publisher 
1.2, and t'ngeSlream 2.1 — are able to output 
acceptable non-PostScript copv on an\' 
printer supported by the Amiga 
Compugraphic fonts 

Indeed, if you own Professional Page 
and a non-PostScript, 300-dot-pcr-inch laser 
printer, you can produce pages as sharp as 
PostScript documents. That's so because 
PPagc's Gompiigraphic fonts can be output 
on any Preferences printer at the printer's 
tiLll resolution. Moreover, Compugraphic 
fonts appear without lagged edges on (he 
screen, unlike PostScript fonts. 

UnlortLinately, these fonts are memorv- 
fiends, so those of you with loi^' memory 
systems may run on t of memory fa i rl y qu ickh' 
if vou're not careful. And there are onlv iwo 



Compugraphic fonts in PPage — Times and 
Trium\irate, while there are myriad 
PostScript fonts to choose from. (Ilowever, 
Gold Disk offers additional disks of 
Compugraphic fonts separately.) 

Compugraphic fonts eat Lip so much 
memorv because they are constructed bv 
PPage as needed. While the standard Profes- 
sional Page fonts rely on the PostScript in- 
terpreter in the printer to form the letters and 
displav them at the desired size, 
CompiLgraphic fonts are constructed by a 
special program on PPage's CGFonts disk, 
using font library data alsostored on thedisk. 
Characters are constructed as the)- are re- 
quired, at the desired size and resolution. 

Characters already constructed bv Pro- 
fessional Page will be stored in a "cache." 
Once a character has been saved to the cache, 
i! no longer needs to be constructed, and the 
program's performance is much impro\-ed. If 
you ha\'e PPage on your hard drive, the fonts 
and the font cache will be saved on that hard 
disk for repeated use. 

1 f you have an Amiga 3000 with 5M B of 
chip RAM, you probably will never have to 
worry about the details of font caching. But if 
you have a system with 512K of chip RAM 
and an additional megabyte of fast RAM, vou 
should learn to control the font caching in 
order to get the best performance possible. 

The easiest way to do this is to start eacli 
Professional Page session by changing the 
default Compugraphic font control \alues. 
First, select Preferences/Compugraphic Pont 
Control on the pull-down menu, which brings 
up the Compugraphic Font Control reqLiester. 
PPage reads the va I lies in this requester het'ore 
using a Compugraphic font for the first time, 
so you should make any modifications at the 
beginning of each session. By adfListing the 
\'alues, yoLi will control the largest character 



^6' Amazi.\g Computisg 



size (in pixels) that can bu storud in tiv RAM 
cachc,thcmaximiimsi7,oofncliara(:terthatis 
stored in chip RAM, the maximum amount of 
RAM cache size bofore data is stored on disk, 
the maximum number of kilobytes of chip 
memory that can be used by the font cache, 
and the maximum number of kilobytes of 
disk space to be used for the font cache. You 
will have to experiment with these numbers 
a bit to achieve good performance, but the 
effort will be worthwhile. 

If changing these values doesn't sa\'c 
enough memory, you should switch off 
PPage's color and/or interlace modes, since 
these options consume tremendous amounts 
of memory and are usually unnecessary . This 
stop alone should pre\'ent most memorv 
problems and increase the program's perfor- 
mance. 

Of course, there is another option: add- 
ing more memory to your system. What is 
important is that you find a way to prodtice 
professional-quality pages without shelling 
out a third of your yearly salary to buy a 
PostScript printer, or investing in one of the 
PostScript interpreters described below. 

On the other hand, if you are planning 
to get serious about electronic publishing, 
PostScript output is recommended. Without 








a PostScript printer, you vvill not be able to 
take full advantage of your DTP program's 
ability to print structured graphics such as 
those produced on drawing programs like 
Professional Draw, 

Unlike bitmap graphics, u'hich are cre- 
ated with paint programs, structured 
graphics don't have jagged edges vvhcn 
printed on PostScript printers. Another ben- 
efit of PostScript compatibility is access to 
publishing's most extensive font library and 
myriad collections of structured clip art. 

If you already have, or have access to, 
a Hewlett Packard LaserJet or compatible 
laser printer, there are farbctter solutions — 
and they are relatively inexpensive. 

At one end of the spectrtmi, there are 
software implementations of PostScript that 
create a PostScript image in your computer 
and send it to the printer. These arc the least 
e>;pensi\'e routes to PostScript, but they are 
too slow for most professional use. 



PostScript Cartridges 

A better option are PostScript car- 
tridges, which can be installed into the 
LaserJet's cartridge slots. Once in place, the 
LaserJet takes on all the attributes and capa- 
bilities of a PostScript 
printer. While these car- 
tridges won't outrun 
most PostScript printers, 
they do provide full 
PostScript functionality 
for under $500. 

The cartridges a re ea sy 
to install, and all of the 
ones I have seen include 
equivalents for the stan- 
dard 35 fonts found in 
Apple's LascrWri ter Plus, 
as well as a mechanism 
for switching between 
PostScript and LaserJet 
modes — an important 
feature, since many pro- 
grams can't output in 
PostScript. Some of the 
most popular cartridges 
are the Adobe PostScript 
Cartridge (Adobe Sys- 
tems), l-'acific Page (Pa- 
cific Data Products), and 
the Hewlett- Packard 
PostScript Cartridge 
(Hewlett-Packard Co.). 

There is, alas, a minor 
catch. Forthesecartridges 
to operate properly, you 



i' 



will probably need to install more memory in 
your laser printer than the standard 512K 
bytes of base memory it came with. I added 
4MB to my HP IIP/Pacific Page set-up, and 
have been very plea.sed with its speedy per- 
formance. You will need a minimum of 2MB. 

PostScript Software 

As mentioned above, printer cartridges 
aren't the only way to achieve PostScript 
output. Your Amiga can do the same thing as 
a PostScript cartridge. This is because 
PostScript is essentially a programming lan- 
guage. Various PostScript interpreters — 
whether in the form of a printer, a printer 
cartridge, or special software — are therefore 
capable of taking a set of PostScript com- 
mands and turning them into instructions for 
printing. 

PixelScript (Pixelations) is one Amiga 
program that docs just that. The cost is a mere 
ij>149 — considerably less than other PostScri pt 
options. While quite slow, PixelScript is ef- 
fective and easy to use. It comes with a 56- 
page manual and five font "families'" in a 
proprietary PixelScript format. The major 
d rawback, besides its speed, is that you cannot 
use fonts other than those produced for 
PixelScript. You can, however, purchase ad- 
ditional fonts from the manufacturer. 

In summar)', if you intend to make a 
business out of desktop publishing, it vvill be 
worth vour time and money to investigate 
the PostScript options discu.ssed above. 
However, if you plan to use your publishing 
program to produce an occasional flyer or 
newsletter, you may decide PostScript is plain 
overkill. 

Whatever you decide, you now know 

that your Amiga can produce pages that are 

as perfect as you care to make them — at a 

fraction of the conventional cost.

Lemmings, The CIA, 

AMOS, 

and Ring War. 



AMOS Everyone! 

AMOS, thu Dnsic langungc inkTprctn- 
[ion from Kuropross Software, is bogitTiiing 
to ninko iin impression in the Fred Fish 
Collection. Fred Fish Disl< 554 has a total of 
fi\'e games or simulations created in 
AMOS. I'rom the old favorite. Mastermind, 
to a quick little version of Sub Attack, 
people have Ixvn using AMOS to create 
entertainment software. Moivever, two 
surprises were IFSgen and Landscape. 
IFSgen (Iterated Function S\'stem genera- 
tor) creates n type of fractal f«r generating 
pictures from snowflnkes to gala.xies 1%'ith 
full control of the features. Likewise, 
Landscape generates entire fractal scenes 
while allowing the ability to manipulate a 
variety of parameters. 

AMOS has opened a field of possibili- 
ties with their AMOS-The Creator, a 
compiler, and now the just released 3-D 
Effects. This arsenal of tools is important to 
anyone dabbling in Amiga programming. 

Touchy Footing 

[wo programs are currently circulat- 
ing in the Commodore Amiga 
redistributable software libraries that 
require extreme caution. Both of these are 
games based on discovering landmines 
with luck, deduction, and an imaginary 
foot (which becomes more imaginarv if voti 
step on an imaginary mine.) Landmines, an 
AMOS game on Fred Fish Disk 554 {please 
see above) and MineClearer on FF54I. 
While Landmines is an interesting 
implementation, MindClearer is remark- 
ably close to a game being sold in 
Microsoft's Window entertainment package 



for MS-DOS computers. The play is simple 
and the graphics are excellent. 

The CIA Connection 

Fred Fish Disk 5Sl) is completely 
dedicated to World Data Bank II for the 
Amiga. This piece of programming is a 
storv in itself- The basic information was 
retrieved frtim the files of the CIA through 
the Freedom of Information .Act. 

As Fred Pospeschil wrote in the 
original MS-DOS version of the World Data 
Batik II program. "The full WDB-II is a 
digitiai map data base produced by the 
Central Intelligence Agency (CIA) and 
distributed by the National Technical 
Information Ser\'ice (NTIS)... WDB-11 is a 
digital representation of the world 
coastlines and bound ries suitable for use in 
aulomaled mapping systems. It contains 
approximately six million discrete 
geographic points and was digitized using 
all available sources of information. Map 
scales used range from 1:750,000 to 
!:4,0[K),0(K1 with a nominal scale of 
L.XOOO.OOd." 

Altluuigh this large amount of 
information is exceedingly helpful in 
creating large scale maps on large plotters, 
the information had to be greatly reduced 
from its original 150-200MB and its 5660.00 
price tag. The current version is derived 
from 3MB of information in ASCII format. 

FF5H0 has three read\' to run pro- 
grams—SAT, SAT8, and VN'DB. SAT and 
SATS produce a spherical view of the Earth 
at any longitude and latitude coordinates 
selected. The SATS version is for use only 
with Amigas containing a math co- 



processor. SATS will crash if a math co- 
processor is not present. WDI5 produces a 
flat map with all the distortions we have 
known since elementary school. Using 
simple slider gadgets to select different co- 
ordinates (you can also select co ordinnates 
by placing the mouse pointer mer the 
desired location — works best in magnifica- 
tion mode) and a \ery easy menu, students 
of all ages will find it very easy to create a 
map of an}' area they need. 

Unfortunately, World Data Bank 11 
falls victim to the same fate that have many 
ctin-ent map makers going full steam, the 
changing boundaries of countries through- 
out Eastern Europe and the countries of the 
once Soviet Union, Hovve\'er, this accu- 
rately depicts coast lines and major rivers. 
It is also a great piece of history to compare 
v\'ith our maps a few years Irom now. 

OH NO! 

In order to publici>^e their newest add- 
on to Lemmings, "OH NO! More Lem- 
mings!," the people at Fsygnosis gave 
cvePi'one a little taste and a Holiday gift 
besides with a Special Christmas Lem- 
mings Demo. The Special Christmas 
Lemmings Demo comes with four le%'els. 
Two le\els ha\'c been created just for the 
holidavs with little Lemmings dressed in 
tiny Santa style outfits and running 
through snow-covered landscapes. They 
make their final escape through holly- 
decorated houses beside bouncing 
snowmen. Although intriguing, these levels 
are fun without producing an abundance of 
tension. 

Hovve\'er, in order to preview their 
latest addition to the Lemmings 
phenominon, Fsygnosis places two difficult 
levels from the collection on the disk. A few 
moments with these levels and you know 
the Fsygnosis guys are trying to create 
sleepless nights throughout the entire 
Amiga community. 

While fsygnosis retains the copyright 
on this disk, they have allowed the disk to 
be freely redistributable. This is the best 
way to experience the fun ai\d trauma of 
Lemmings, and it is a welcomed gift from

ASDG's Charityware 

y\SDG also has a gift for the Amig.l 
community. Rin^Wiir, a vcctor-bn.sed shoot 
'em up game, was written by ASDG staff 
member Eric [3azan. Tlie game is cop)'- 
righted hv Mr. Bazan, but it is freely 
redistributable. The graphics are based on 
old arcade games such as Aslcivkif and 
rcDJ/K'!;/. The goal of the game is to 
penetrate through three rotating rings and 
ixit a fi\-e-pointed star in the ring ship at the 
center of the rings. At the same time, you 
must avoid mines and the ringship it.self. 

Punch a hole into one of the segments 
of the rings, .ind destroy the inner ship. 
This advances you to the next le\'el. Also, 
watch out for the mines — they randomly 
warp into the game and chase you. 

Instead of sending a voluntary' 
donation to tlie author, ASDC provides 
addresses of three national charities — The 
American Red Cross, The American Cancer 
Society, and TTie Muscular Dystrophy 
Association. ASDG asks you to choose a 
charity and send a SIO donation. The 
addresses appear during the game's 
opening credits. For more information,

Educating Amiga 

by jeff Gamble 




Can you imagine what it might hnvc been 
like toproduce your own televisionshow\vhen 
you were in the third grade? How about using 
DchtxcPaint IV, the Video 7'iws(('r,and an Amiga 
2500 to draw and paint in art class? The viuing 
students at the Bumeil Laboratory School in 
Bridgewater, Massachusetts, do it ever;' dav. 

B.E.5.T., Bumeil School lilementaiv Tele- 
vision, is the means thnuigh which these stu- 





fir;>vcn. 




From top to bottom: Derek Marconi's "Super Derek," 
Michael Ducotis"Michaelangelo," and Jennifer Wood's 
"Computer."

dents express their artistic talents and working 
relationship vvith the Amiga. The Burnell stu- 
dents create two television shows a month. Big 
B.E.S.T. and Little B.E.S.T., participating in all 
aspects of production. Their advisor, 
Bridgewater State College Media Scr\'ices As- 
sistant Rich Gopen, says the kids really enjoy 
producing the shows and working with the 
.Amiga, The students use an Amiga 2500, 
equipped with a Video Toaster and 
an Amiga .500, for their creations. Mr. 
Gopen mentioned that although they 
have experienced some minor diffi- 
culties with their Toaster, NewTek 
has provided excellent technical sup- 
port and he is quite satisfied with the 
unit's performance. The 2500/Toaster 
combination is used mainly for show 
production, but both units are used 
quite frequently by the Burnell kids 
for their drawing, painting, and ani- 
mation projects. The kids from B.E.S.T. 
were also featured at a recent televi- 
sion, film and video production festi- 
VcA, A'ii/.'i, GiHicra, Ai:twiil held at the 
World Trade Center in Boston. 

Television production is just one 
aspect of tlie students' Amiga experi- 
ence. Three Bumeil students, Derek 
Marconi, Michael DuColt, and Jen- 
nifer Wood, entered their drau'ings, 
created on the Amiga s, in the Boston 
Computer Society's 1991 Youth 
Compul-est and won. Derek, \vho 
won first place in the K-3 division, 
digitized his face with DipVint' and 
placed it in a drav\'ing created with 
DduxcPaint III and an A25t)0. Michael 
took first in the 4-6 grade division 
with his rendition of Teenage Mutant 
Ninja Turtle Michaelangeio, created 
on an Amiga 500. Jennifer won sec- 
ond place in the grade 7-9 division 
with her drawing titled "Computer" 
which was created on the 25011, 
Michael's pictureivas featured on the 



cover of the October 1991 issue of BCS Update, 
one of the Boston Computer Societv's maga- 
zines. 

Mr, Gopen, the students' advisor, said 
that he'd like to see more Amigas to work with 
but that the college is not too keen on dealing 
vvith Commodore. Bridgewater State received 
their first Amigas in 1988 when CBM sent three 
Amiga 250n's for use at the campus as part of 
an education program. Mr. Gopen mentioned 
that Bridgewater State was going to recei\'e a 
large grant to build a technical center for K-12 
education. He said that unfortunately, the col- 
lege was not interested in the .Amiga because 
of the school's relationship with Commodore. 
This is unfortunate since the technical center 
would be an excellent opportunity for Com- 
modore to show off the pouer of the Amiga 
and to teach and inspire young minds. 

It certainly would have been wonderful 
to ha\'e been able to use an Amiga in the third 
grade. The Burnell Laboratory School students 
are doing an excellent job. More young stu- 
dents should be given such an exciting oppor- 
tunitv.
